噪声病的预防和PA喇叭及音箱纯音检测的问题  发帖心情 Post By:2011-12-29 11:29:59 [只看该作者]

     在职业病中有噪声病的预防一类,要求人耳听到的噪声不能超过85dB,但我们的PA喇叭和音箱在做纯音检测时,声压级肯定大于85dB,时间长了肯定会对人耳有损害,造成噪声病,声压级小了,喇叭及音箱的杂音之类又听不出来了,达不到检测的目的,那么有没有什么好的方法解决呢,即能检测好喇叭和音箱,又不致对人耳造成伤害,引起噪声病呢?

High-Fidelity Hearing Protection

Musicians Earplugs? are custom high-fidelity earplugs developed by ETYMOTIC over 20 years ago, following president Dr. Mead Killion’s participation in a noise study for the Chicago Symphony Orchestra. They are still the highest fidelity of any earplugs available. Musicians Earplugs are a custom product, made individually for each user. They can be purchased from licensed hearing professionals.

Musicians practice and perform in a variety of different settings. They are exposed to high levels of sound, sometimes for long periods and may require different amounts of protection depending on sound levels encountered during rehearsals and performance. Some musicians use one type of attenuator in one ear and one type in the other, depending on the source and location of the sound.

  • Benefits
    • Reduces sound levels evenly so that music and speech are clear and natural, not muffled as with other earplugs
    • Reduces risk of hearing damage for many noisy occupations and noisy venues, such as airshows, parades, athletic events and motor sports
    • Enhances the music experience for audiences while protecting hearing
    • Lets musicians hear their own instrument and their blend with others
  • Features
    • 3 levels of sound reduction: 9 dB, 15 dB and 25 dB
    • Interchangeable buttons
    • Custom earmolds require ear impressions
  • Tips
    • Regular use of these high-fidelity earplugs while practicing, performing and listening to music will protect hearing from the cumulative effects of overexposure to loud sound throughout life.
    • A little time may be required to acclimate to these earplugs. Many musicians report that they hear their own instruments better, as well as the balance with those around them.

意思就是耳塞

不影响你纯音判断音色判断和音效判断的前提下,把入耳的灵敏度降下来
