耳道痕癢耳屎作怪?
耳仔痕癢我們會自然地用手抓,如果耳道痕癢呢?用棉花棒或採耳棒掏挖?耳道痕癢可能因為耳垢太多,刺激外耳道神經引致痕癢;或者耳朵進水感染真菌或細菌。而從中醫角度來看,耳道痕癢亦與風熱濕毒、血虛風燥或腎陰虛有關,風熱濕毒的人通常伴有耳脹悶不適,或出現低音調耳鳴,耳廓周圍皮膚發紅灼熱,流膿水,需要祛風清熱,除濕解毒。
血虛風燥人士耳廓皮膚粗糙、增厚、乾裂脫皮,伴隨食慾不振、身倦乏力的症狀,宜養血祛風,健脾和胃。
腎陰虛的人外耳道奇癢難忍,伴隨症狀為耳脹悶或耳內蟬鳴、腰痠乏力、耳鳴眩暈,需要補腎降火。
耳道痕癢不宜自行掏挖,容易使耳道受傷出現發炎等情況,想紓緩耳癢可嘗試用雙手按壓耳屏或拉拉耳垂,長遠還是建議尋求醫生或註冊中醫師意見,用專業儀器協助檢查耳道狀況,採取最合適的治療。

Is earwax the cause of itchy ear canal?
We will naturally rub our ears when they are itchy, but how about the ear canal? Do you use Q-tip or ear pick to get the job done? Itchy ear canal could be caused by accumulation of earwax, which might trigger the nerves along the canal’s exterior; it might also itch when water enters by accident and cause a bacterial or viral infection.
From the perspective of Chinese Medicine, itchy ear canal is related to the hot wind and dampness pathogens, asthenic blood and dryness, as well as yin deficiency in the kidney.
Individuals under the influence of the hot wind and dampness pathogens will normally experience swelling and discomfort, low-frequency tinnitus, redness and burning sensation on auricle (the visible part of the ear), and pus in the ear. People with these conditions must eliminate wind, heat, dampness and toxins from the body.
As for individuals with blood deficiency and dryness in the body, their auricle would be dry and thick; the skin might peel off easily. They may also experience appetite loss and fatigue, and need to nourish the blood, eliminate wind in the body, as well as strengthen the spleen and the stomach.
People with yin deficiency in the kidney will feel an unbearable itch. Other accompanying symptoms are ear swelling and discomfort; cicada-like noise in the ear, backache, tinnitus and dizziness; therefore, they need to replenish to the kidney and clear the heat from the body.
It is not advisable to clean ear canal on your own, as you might risk causing inflammation. In order to relieve the itch, try messaging the tragus (the small pointed eminence of the external ear) or earlobes. Seek medical advice from registered and licensed Chinese medicine practitioner for long-term solutions, as they will be able to monitor the ear canal’s situation using professional medical equipment, and customize the right treatment for you.

【優質睡眠】但願每晚都能Sleep like a baby
#除了嬰兒大人都可以有睡前儀式
#歡迎分享你的助眠法寶
#星期六放輕身心
四大助眠法寶
睡覺是人體自然的休息機制,但人越大越發覺,因為環境、健康、情緒、壓力等等原因,睡不安寧和失眠已成為常態,一覺好眠彷彿成為了奢侈品。除了病向淺中醫解決導致失眠的原因外,還可以利用一些法寶幫助睡眠。
眼罩
戴眼罩的目的最主要是遮光,所以良好的遮光性是必備條件,最基本是眼罩四邊和鼻樑位不會漏光。此外坊間還推出有附加功能的眼罩,例如可熱敷或冷敷,加入精油,甚至加入保濕、改善皮膚質素等美容功效。
耳塞
眼睛可以自行閉上,耳朵卻沒有關閉功能,所以對聲音敏感的人,想隔絕聲音的騷擾睡覺得靠耳塞了。不過有個壞處是戴耳塞令人減低警覺性,萬一有火警發生,隔音功能超級好的耳塞就會令你置身於危險之中。
抱枕
枕頭一般都枕在頭和頸之下,以承托頭顱和頸椎,漸漸發現床上應該多放幾個枕頭或抱枕,仰睡時墊在腳下有助血液回流,側睡時在腹部抱一個抱枕異常舒服,找個枕頭放在兩膝之間,更有利於放鬆腰背部肌肉,孕媽媽欠缺抱枕有時更難以入睡呢。
電風扇
睡房的溫度對睡眠有很大影響,除了利用冷氣調節溫度,電風扇是另一個經濟又有效的選擇,開電風扇可以讓房間保持通風涼爽,還能製造「白噪音」——低分貝的背景聲音頻率,大自然中類似的聲音有流水聲、海浪聲等,不少人聽著白噪音會有助入睡。
4 treasures to improve sleep quality
Sleeping is the natural rest mechanism of the human body. As people get older, they commonly have sleep issues such as insomnia and difficulty falling asleep due to factors related to environment, health, emotions and stress. Good sleep is very valuable. In addition to seeking professional advice to resolve insomnia, you can also use these gadgets to improve sleep.
Eye mask
The main purpose of wearing an eye mask is to block light, so it is important to ensure your eyemask is properly positioned to not leak light.
In addition, there are some eye masks with additional functions, such as hot or cold compresses function, adding essential oils, or even adding moisturizing agents to improve skin quality and other beauty effect.
Earplug
You can close your eyes but not ears. Therefore, people who are sensitive to sound, need the earplugs to isolate from noise. However, it is harmful that the earplugs reducing your alert. If there is a fire, the earplugs with great sound insulation will put you at risk.
Body Pillow
Pillows are generally placed under the head and neck to support the skull and cervical vertebrae. Gradually it seems that there should be more pillows and body pillows on the bed. When sleeping on the back, it will help the blood to flow back by placing a pillow under the feet. When sleeping on the side, holding a pillow in the abdomen is very comfortable. Find a pillow to place between the knees is conducive to relaxing the waist and back muscles. It is more difficult to fall asleep for pregnant women without pillows.
Fan
The temperature of the bedroom has a great impact on sleep. In addition to using the air conditioner to regulate the temperature, fan is another cheap and effective choice. Fans can keep the room well ventilated and cool, and can also create "white noise" - low decibel background sound frequency, similar sounds in nature are running water, sounds, waves. White noise helps many people fall asleep.

GRANDIOSO K1X
"Two revolutions integrated. Two revolutions connecting people to music... The VRDS-ATLAS and Master Sound Discrete DAC - now come to fruition in an integrated player that carries the name… Grandioso ( Grandioso (music): Grand or noble)."
An unprecedented transport mechanism that invites you to the furthest reaches of sound.
VRDS (Vibration-Free Rigid Disc-Clamping System) is Esoteric's unique CD/Super Audio CD transport technology, which has been specially designed to clamp the disc to a same-diameter turntable in order to eliminate the disc's rotational vibration, as well as any extraneous vibration emanating from the mechanism itself. It also corrects any warpage of the disc, dramatically improving the accuracy of both the optical pickup and the disc pit layer's corresponding optical axis, while also minimizing servo current. This all adds up to dramatically reduced disc read error for exceptional audio quality.
The new VRDS-ATLAS platform boasts unprecedented mechanical perfection and superlative audio quality, with heavyweight construction that is fully 127% heavier than previous iterations (6.6kg for the mechanism alone, and 13.5kg including its base). This highest rigidity and weight in the history of VRDS mechanisms has the effect of greatly reducing any and all vibration that could adversely affect audio quality. The transport's larger new side panels and bridge are all formed of SS400 steel, and its turntable is made from duralumin, which is renowned for its excellent sound quality. Also, its spindle features a newly designed thrust bearing system, for a friction-free one-point spindle support system that ensures smooth, noiseless turntable rotation.
Esoteric's impressive VRDS-ATLAS is the quietest and most elegant transport in the history of VRDS. The key to achieving this was a resolute focus on mechanical grounding technology that more effectively reduces vibration.
Adopting a wide & low-profile design for the entire mechanism helped achieve a lower center-of-gravity, and relocating the turntable motor to below the turntable from its previous position above the bridge dramatically shortened the route for grounding vibration and reducing mechanical noise. Tray hollowing has also been minimized for increased rigidity, and special stoppers made from vibration-absorbing elastomer cancel out resonance when the tray is stored.
The Grandioso K1's mighty power supply was the key to its powerful and profound three-dimensional sound. With the introduction of its new X version, this power supply has been dramatically enhanced to add further depth to its exceptional audio tone. Its built-in D/A converter features independent power transformers for left and right channels, and the K1X includes a total of four independent toroidal power supply transformers. Furthermore, technologies cultivated in the development of the Grandioso P1X/D1X have also been adopted, including a new low-feedback DC power supply regulator featuring a discrete circuit configuration which contributes to its powerful open sound. The K1X also contains a total of 76 EDLC* supercapacitors (with a total capacity of 2,050,000µF or 2.05F). This greatly increased power supply capacity provides a tremendously improved sound quality for exceptional resolution in the lower frequency ranges.
*EDLC (Electric Double-Layer Capacitor):A special type of capacitor boasting an astoundingly high capacity compared to the electrolytic capacitors used in conventional audio equipment.
The VRDS-ATLAS transport mechanism is centrally located within the chassis, where it is fixed to a 5mm-thick steel bottom plate and supported by four proprietary pinpoint feet (patent no. 4075477 and 3778108). This effectively isolates the rotational mechanism from vibration. The internal structure of the chassis features a double deck design, with the audio boards on the upper level and power supply circuits and transformers on the lower level to minimize magnetic flux leakage and vibration, while also shortening the power supply wiring.
Semi-Floating Top Panel
The enclosure's top panel utilizes a screwless semi-floating structure that further contributes to an open and expansive sound.
Master Sound Discrete DAC
Bringing out all the dynamics and energy of the original master recordings.
Master Sound Discrete DAC Bringing out all the dynamics and energy of music.
Unattainable by integrated chips, our goal was to assemble carefully selected and tested discrete components into a complete circuit that could perfectly reproduce all the dynamics and energy of music. Our top engineering teams put their pride on the line to design and produce a quality of sound that can only be found in the Master Sound Discrete DAC discrete D/A converter.
The K1X's Master Sound Discrete DAC is the most revolutionary two-channel stereo DAC circuit in Esoteric's history, and is based on the original circuit developed for the Grandioso D1X monaural D/A converter.
As an extension of the D1X's design philosophy, a luxurious volume of materials have been invested in the construction of K1X's Master Sound Discrete DAC. For example, it features 32 separate elements for each channel. Key components such as a clock driver, logic circuit, and capacitors and resistors, are kept independent for each of these 32 elements to ensure the purest output without no loss of musical energy.
The K1X's independently developed Δ∑ modulator supports 64-bit/512Fs and the latest high-end digital formats, including of 22.5MHz DSD and 768kHz PCM signals. The FPGA's* dedicated digital processing algorithm was developed exclusively for the Master Sound Discrete DAC, and has been fully optimized for outstanding playback of both DSD and PCM digital audio data.
Advanced Quality Control
With a discrete DAC, where component tolerances are directly linked to arithmetic precision, highly advanced quality control is also required for the manufacture of electronic circuit boards. Esoteric's own in-house factory boasts some of the world's leading board mounting technologies, such as soldering performed in an oxygen-free furnace, which is located in a clean room featuring the same level of cleanliness found in a hospital operating room. Technologies cultivated in the production of electronic circuit boards for audio, medical, aerospace, and defense industries support the high production quality of the Master Sound Discrete DAC.
The ESOTERIC-HCLD output buffer amplifier boasts an amazingly high-speed slew rate (response speed) of 2,000V/µs. Current transmission and speed—the most important factors for an analog output circuit—have been pushed to the limits to reproduce the reality of music with a dynamic range that is truly breathtaking.
In addition to its XLR and RCA amplifier line connections, the K1X also features the ES-LINK Analog method of current transmission. Taking full advantage of the HCLD buffer circuit's powerful current supply makes the K1X less susceptible to the detrimental effects of impedance on the signal route. It also enables a more powerful signal transmission, fully driving connected compatible devices.
A high-accuracy clock circuit is the key to achieving superlative sound quality in digital audio playback. A top-quality clock circuit is truly the heart of any high-end digital player. The K1X now features the superb Grandioso Custom VCXO II clock originally developed for the Grandioso P1X/D1X. This clock was developed with carefully considered modifications made to the earlier model's internal circuitry and components to more vividly emphasize the K1X's ultimate audio quality while further boasting remarkably low phase noise and excellent center precision (±0.5ppm).
The K1X can also be connected to the Grandioso G1 Master Clock Generator for playback, with internal circuits synchronized to a 10MHz clock that features the same high precision as an atomic clock, enabling further pursuit of high sound quality.
D/A Converter Functions for External Input, D/D Conversion, MQA Support & USB Input
In addition to its coaxial and optical inputs, the K1X also features a USB type-B port that is compatible with both 22.5MHz DSD and 768kHz/32-bit PCM asynchronous signal transmission, thus enabling it to also be used as a stand-alone D/A converter. Functions are provided for upsampling a PCM digital signal to 2/4/8/16× (max. 768kHz) and converting PCM to DSD. The K1X is also compatible with MQA-CD decode playback and full MQA decoding for playback of various digital inputs including USB.*
*MQA certification is pending as of August, 2019, and support is scheduled to be added via a software update as soon as certification is complete.

白噪音在聲音的頻譜中,它從高頻到低頻平均分配。就如同一道牆,能夠屏蔽很多細節,讓你沒有意識到聲音的變化。絕對理想的白噪音是不存在的,而大自然的聲音是最接近白噪音的聲音。
ホワイトノイズは、人間の耳の可聴周波数範囲(20〜2000KHZ)で同じパワーで連続的に放出される音です。 聴覚システムは、いつでも待機している警報システムのようなものです。私たちが眠っているとき、「突然の」音が現れ、脳はこれらの突然の音を検出して警告を発し、睡眠に影響を与えて目を覚まします。
ホワイトノイズは音のスペクトルにあり、高周波から低周波まで均一に分布しています。 壁のように、細部を遮ることができるため、音の変化に気付くことはありません。 絶対に理想的なホワイトノイズは存在せず、自然の音はホワイトノイズに最も近い音です。
White noise is a sound that is continuously emitted with the same power in the audible frequency range of the human ear (20~2000KHZ). The auditory system is like an alarm system on standby at any time. When we are sleeping, "sudden" sounds appear, and the brain detects these sudden sounds to generate alertness, which affects sleep and wakes up.
White noise is in the sound spectrum, and it is evenly distributed from high frequency to low frequency. Just like a wall, it can shield a lot of details, making you unaware of the changes in sound. Absolutely ideal white noise does not exist, and the sound of nature is the sound closest to white noise.
백색 소음은 사람의 귀의 가청 주파수 범위 (20 ~ 2000KHZ)에서 동일한 파워로 지속적으로 방출되는 소리입니다. 청각 시스템은 대기 상태의 경보 시스템과 같으며, 잠을 자면 "갑작스러운"소리가 나타나고 뇌는 이러한 갑작스러운 소리를 감지하여 수면에 영향을 미치고 깨어납니다.
백색 잡음은 사운드 스펙트럼에 있으며 고주파에서 저주파로 고르게 분포됩니다. 벽과 마찬가지로 많은 세부 사항을 보호하여 소리의 변화를 인식하지 못합니다. 절대적으로 이상적인 백색 소음은 존재하지 않으며 자연의 소리는 백색 소음에 가장 가까운 소리입니다.
เสียงสีขาวเป็นเสียงที่เปล่งออกมาอย่างต่อเนื่องด้วยกำลังเดียวกันในช่วงความถี่ที่ได้ยินของหูมนุษย์ (20~2000KHZ) ระบบการได้ยินเปรียบเสมือนระบบเตือนภัยเมื่ออยู่ในโหมดเตรียมพร้อมตลอดเวลา เมื่อเราหลับ เสียง "กะทันหัน" จะปรากฏขึ้น และสมองจะตรวจจับเสียงกะทันหันเหล่านี้เพื่อสร้างความตื่นตัว ซึ่งส่งผลต่อการนอนหลับและตื่นขึ้น
สัญญาณรบกวนสีขาวอยู่ในสเปกตรัมเสียง และกระจายอย่างสม่ำเสมอจากความถี่สูงไปยังความถี่ต่ำ เช่นเดียวกับกำแพง มันสามารถปกป้องรายละเอียดได้มากมาย ทำให้คุณไม่รู้ถึงการเปลี่ยนแปลงของเสียง ไม่มีสัญญาณรบกวนสีขาวในอุดมคติอย่างแท้จริง และเสียงของธรรมชาติเป็นเสียงที่ใกล้เคียงที่สุดกับเสียงสีขาว
Tiếng ồn trắng là âm thanh được phát ra liên tục với cùng công suất trong dải tần có thể nghe được của tai người (20 ~ 2000KHZ). Hệ thống thính giác giống như một hệ thống báo động ở chế độ chờ bất cứ lúc nào, khi chúng ta đang ngủ sẽ xuất hiện những âm thanh "đột ngột", não bộ sẽ phát hiện ra những âm thanh đột ngột này để tạo ra sự tỉnh táo, ảnh hưởng đến giấc ngủ và thức giấc.
Tiếng ồn trắng nằm trong phổ âm thanh, và nó được phân bố đều từ tần số cao đến tần số thấp. Cũng giống như một bức tường, nó có thể che chắn rất nhiều chi tiết, khiến bạn không nhận biết được những thay đổi của âm thanh. Tiếng ồn trắng lý tưởng tuyệt đối không tồn tại, và âm thanh của tự nhiên là âm thanh gần nhất với tiếng ồn trắng.
White noise adalah suara yang terus menerus dipancarkan pada intensitas yang sama dalam rentang frekuensi (20~2000KHZ) yang dapat didengar oleh telinga manusia. Sistem pendengaran itu seperti sistem alarm yang selalu siaga. Saat kita tidur, akan ada suara “mendadak”. Saat otak mendeteksi suara yang tiba-tiba ini, maka akan menimbulkan kewaspadaan dan mempengaruhi tidur dan terjaga.
White noise terdistribusi secara merata dalam spektrum suara dari frekuensi tinggi ke frekuensi rendah. Sama seperti dinding, ia dapat melindungi banyak detail dan membiarkan Anda mengabaikan perubahan suara. White noise yang benar-benar ideal tidak ada, dan suara alam adalah suara yang paling dekat dengan white noise.
Il rumore bianco è un suono che viene emesso continuamente alla stessa intensità all'interno della gamma di frequenze (20~2000KHZ) che l'orecchio umano può sentire. Il sistema uditivo è come un sistema di allarme sempre in allerta.Quando dormiamo, ci sarà un suono "improvviso".Quando il cervello rileva questo suono improvviso, causerà la vigilanza e influenzerà il sonno e la veglia.
Il rumore bianco è distribuito uniformemente nello spettro sonoro dall'alta frequenza alla bassa frequenza. Proprio come un muro, può proteggere molti dettagli e permetterti di ignorare i cambiamenti nel suono. Il rumore bianco assolutamente ideale non esiste e il suono della natura è il suono più vicino al rumore bianco.
Ang puting ingay ay isang tunog na patuloy na inilalabas sa parehong lakas sa loob ng saklaw ng dalas (20 ~ 2000KHZ) na naririnig ng tainga ng tao. Ang auditory system ay tulad ng isang alarm system na laging naka-alerto. Kapag natutulog tayo, magkakaroon ng isang "biglaang" tunog. Kapag nakita ng utak ang biglaang tunog na ito, magdudulot ito ng pagkaalerto at makakaapekto sa pagtulog at paggising.
Ang puting ingay ay pantay na ipinamamahagi sa tunog ng spectrum mula sa mataas na dalas hanggang sa mababang dalas. Tulad ng isang pader, mapoprotektahan nito ang maraming mga detalye at hahayaan kang balewalain ang mga pagbabago sa tunog. Ganap na perpektong puting ingay ay hindi umiiral, at ang tunog ng kalikasan ay ang tunog na pinakamalapit sa puting ingay.
