Providing quiet areas where workers can gain relief from hazardous noise sources (e.g., construct a sound proof room where workers' hearing can recover – depending upon their individual noise level and duration of exposure, and time spent in the quiet area).
How does noise affect us?
Noise can not only affect us at home, but it can also affect us in the workplace. Although every workplace is bound by the Control of Noise at Work Regulations 2005, industries such as construction, mining and entertainment (nightclubs, theatres and music etc) are the most common places where noise can become an issue. The most common sources of excessive noise levels in these industries are heavy machinery, plant vehicles and loud music/instruments. It wouldn’t be possible to remove these sources from these industries as they are integral to their operation, but there are steps that can be taken to protect hearing, thereby preventing conditions like those discussed earlier.
Why is loud noise painful?
It doesn’t take an acoustics expert to conclude that a large vibration will cause damage to sensitive components of our ear, which is why loud noises can often be uncomfortable and in some cases, painful. Burst eardrums and conditions like acoustic shock are incredibly painful and can cause lasting damage to someone’s hearing, not only affecting their ability to carry out everyday activities, but also their overall quality of life.
Why does Arlene Phillips have tinnitus?
Conditions such as tinnitus and hyperacusis are more prolonged in their development and are caused by constant exposure to excessive noise levels. As with damaged eardrums and acoustic shock, these conditions are as a result of damaged components of the ear, and can be caused by something as mundane as listening to loud music through headphones. Former Strictly Come Dancing judge Arlene Phillips has recently come out and spoken of her struggle with tinnitus, which she blames on the years she spent listening to rock band AC/DC. At the age 75, she has only just discovered she suffers from the condition, but has spoken in The Sun newspaper about the regret she feels for not taking better care of her hearing in her youth:

However, it is important to be aware and to stay vigilant to ensure that our health and wellbeing is protected, and to keep our environment from further harm.
Why do my ears make noise?
The inner workings of our ears are incredibly sensitive and delicate, and are prone to damage if not treated carefully. All noise is caused by vibrations in the air, which are picked up by tiny hairs in our ear canal and then travel to our inner ear. Without getting into PhD-level acoustics, the louder the sound is, the larger the vibration.

Why is noise pollution not funded?
Noise pollution control in residences is not funded by the federal government in part because of the disagreements in establishing causal links between sounds and health risks, since the effect of noise is often psychological and also , because it leaves no singular tangible trace of damage on the human body. For instance, hearing loss could be attributed to a variety of factors including age, rather than solely due to excessive exposure to noise. A state or local government is able to regulate indoor residential noise, however, such as when excessive noise from within a home causes disturbances to nearby residences.

How does noise affect hearing?
Hearing loss is the third most common chronic health condition in the US. Almost twice as many people report hearing loss as report diabetes or cancer. Noise exposure away from your job can damage your hearing just as much as working in a noisy place. Being around too much loud noise—like using a leaf blower or going to loud concerts—can cause permanent hearing loss. And once it’s gone, you can’t get it back! You can have hearing loss before you even notice you’re having problems. Noise is measured in what are called decibels (dB). Over time, listening to loud sounds at high dB levels can cause hearing loss—or other hearing problems like a ringing sound in your ear that won’t go away. The louder a sound is, and the longer you are exposed to it, the more likely it will damage your hearing. The more often you are exposed to loud sounds over time, the more damage occurs. It’s important for healthcare providers to ask about hearing and to screen those who are at risk.
