How is sound measured? 声音如何测量？
Intensity
强度 It‘s the sound‘s ―loudness‖ or ―volume‖. Intensity is measured in decibels (dB). 它是声音的响度或音量。强度以分贝（dB）衡量。
Frequency

Different types of hearing loss 不同类型的听力损失
Conductive
– outer ear to footplate of the stapes
Ear
nerve damage due to exposure to loud noise.
耳蜡堵塞了外听道
Food
由于暴露在高噪声下导致的耳朵神经损伤
Anemia.
allergies.
食物过敏
Reactions
贫血 to medications. trauma or infections.
There is really no such thing as ―tough ears‖ or ―getting used to it‖. 并没有所谓的类似“耳朵耐性强”或“习惯了高噪声的环境“。

Hearing Conservation Training
Environmental Health and Safety University of Tennessee
Did You Know?
About 30 million workers are exposed to hazardous noise on the job. One in 4 of these workers (or 7.5 million Americans) will develop permanent hearing loss.
OSHA Regulation (29 CFR 1910.95) Goal - prevent hearing loss
associated with high noise levels at work
NoNisoeiseEExpxpoossuurree Aatt WWoorkrk
This presentation will cover the following topics:
• The longer and louder the noise, the greater chance permanent damage will occur.
1. Identify potential sources of hearing loss
2. Learn how to prevent hearing loss at work
3. Meet regulatory requirements
4. The purpose of audiometric testing and how it works
• Noise above 140 decibels causes pain and immediate hearing loss.
Signs of Hearing Loss
Difficulty hearing people speak. Inability to hear certain high-pitched or soft
sounds. Noise or ringing in ears. Getting complaints that the radio or tv is too
loud.
Long Term Exposure to Noise
• Our ears can recover from short exposure to loud noise, but over time nerve damage will occur.
The following factors can affect hearing loss:
Noise Intensity or Sound Pressure Frequency or Pitch of sound Length of Daily Exposure Duration of Exposure in Years Individual Susceptibility Other Factors (disease, genetics,
How is Noise Measured?
Noise levels are measured in decibels (dB)
Decibels are not linear measurements
The difference in energy between 100 decibels and 110 is not 10% actually is 100 times the sound level pressure
▪ Loud noise damages or destroys the nerves in the inner ear.
▪ Another effect can be “tinnitus” or permanent ringing in the ear.
Factors Affecting Hearing Loss
Noise-induced hearing loss is the most common occupational hazard for American workers
Hearing loss from noise is slow and painless; you can have a disability before you notice it
If you must raise your voice to speak with someone only 3 feet away, you are in high (hazardous) noise.
It is 100% preventable
Hearing Conservation
Noise Conservation is also called the Noise Standard and is regulated by OSHA (Occupational Safety and Health Administration)
Effects of exposure to loud noise
▪ Exposure to loud noise will inevitably cause hearing loss over time.
▪ Once the nerves of the inner ear are destroyed or damaged from exposure to e noise, the damage is permanent
lifestyle, age, etc.)
When is Noise Too Loud?
• Noise is measured in units called “decibels” or “dB”
• If two people 3 feet apart must shout to be heard, the background noise is too loud (above 85 decibels).
