This is the full text of the Sound Advice Working Group introduction to its recommendations for controlling noise in the music and entertainment industry. 1.1 Music is perceived as pleasant but can sometimes be loud to produce its effect, while the sound of a jet engine, for example, is regarded as unpleasant. 1.2 The music and entertainment industries are unique in that high noise levels and extremely loud special effects are often regarded as essential elements of an event. 1.3 Reducing noise risks in music and entertainment is not about destroying art, but about protecting people - artists, performers and ancillary workers equally. 1.4 The purpose of this guidance is to provide practical advice on developing noise-control strategies in the music and entertainment industries to prevent or minimise the risk of hearing damage from the performance of both live and recorded music. 1.6 Risk assessments of the work should identify those people who are likely to be at risk.
1.7 Everyone in the production chain has a role to play in managing the noise risks - whether it is the promoter selecting a balanced line-up, a performer working with reduced monitor levels or stagehands using their earplugs.
1.8 The Control of Noise at Work Regulations 2005 (the Noise Regulations) require employers to prevent or reduce risks to health and safety from exposure to noise at work, so far as is reasonably practicable. 1.9 The duties in the Noise Regulations are in addition to the general duties set out in the Health and Safety at Work etc Act 1974 (the HSW Act).
1.10 This guidance applies to premises where employees or the self-employed are present, where live (whether amplified or not) or recorded music is being played for entertainment purposes at noise levels which will result in performers' or other workers' daily personal noise exposure being likely to exceed the exposure levels in the Noise Regulations.
The Noise Regulations mean operators of entertainment premises must protect their employees' hearing to a higher standard than the 1989 Noise at Work Regulations, which they replace.
Employers are required to reduce exposure to noise and provide hearing protection and health surveillance including hearing tests (where appropriate) to employees directly involved with loud noise, such as musicians, DJs and bar staff. One Council has worked hard over the last two years to raise awareness of this change in the law and encourage bars, clubs and theatres to carry out workplace assessments and plan any changes needed to comply with the new Regulations. The Council recognises existing licensed premises may find it difficult to carry out major building modifications immediately, but officers do expect employers to assess how best to protect employees from loud noise and come up with short-, medium- and longer-term solutions. New businesses will be expected to incorporate noise-control measures during the design stage. The Council wishes to take a staged and proportionate approach to enforcement although it will use statutory powers if employers fail to meet their obligations. 1.14 The Noise Regulations require employers to take specific action at certain action values. 1.17 Look at Useful information and glossary for a table of the actions required based on a comparison of exposure action values and exposure limit values. 1.18 The noise exposure level (often referred to as the 'noise dose') takes account of both the sound pressure level and how long it lasts. 1.19 Each 3 dB added doubles the sound energy (but this is only just noticeable to a listener). A noise level reduction of 3 dB halves the sound pressure level (and its propensity to damage). 1.20 Halving the noise dose can be achieved either by halving the exposure time, or by halving the noise level, which corresponds to a reduction of 3 dB.
1.22 It is important that people consider noise exposure when not at work because cumulative exposure leads to hearing damage, whether or not it is work-related.
Martin first noticed he had a problem when the ringing in his ears after a show never really disappeared, but became a permanent and very annoying feature of life. For the most part Martin has had to give up live engineering and has had to make a living as a 'system tech' and administrator for a PA rental company.
This list is not definitive but indicates the jobs of people working in the music and entertainment sectors that might be affected by loud noise from live or amplified music or special effects.
Frequency analysis: The breakdown of sound into discrete component frequencies, measured in Hertz and usually grouped in bands or octaves. Noise exposure: 'The noise dose', which can be calculated, takes account of the actual volume of sound and how long it continues.
The event safety guide - A guide to health, safety and welfare at music and similar events.
The charts on this page will show you different noise levels for specific jobs, tools, and various situations.
For example, a backhoe and a compressor each producing 90 dB have a combined output of 93 dB, not 180.
The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion.
These electrical impulses are transmitted to the hearing (auditory) nerve and up to the brain, where they are interpreted as sound. Over the past few days some folks have been taking the defibrillator to the long gone IGOTD about FPSRussia.
A quick trip to Dangerous Decibels will tell you that any sound above 85 db can cause permanent hearing damage, dependent on exposure time. Multiply that by all the other mags you shoot every time you hit the range and every range trip you’ve ever taken.
We here at TTAG have long argued that silencers should be available for any gun in any state of the union without any governmental interference. Do the research, get the facts and the next time you go out shooting do yourself a favor; wear ear protection.
Ryan Finn is the Director of Operations and an Associate Instructor for Montana Tactical Firearms Instruction as well as a contractor for Vanguard Security Consultants when he isn't writing for TTAG. I find the main difference between shooting indoors and outdoors is that outdoors (particularly on a pistol-only range) I can get away with just plugs or just muffs.

That is why approximately 100% of the vets who apply for it get the 20% hearing disability.
I (while not wearing ears) once stood behind my wife while she was working with her Ruger LCP…at an outdoor range. The tinnitus is mild, but always noticeable in quieter environments…stemming from ONE unprotected loud blast. I’d also like to point out that purposefully impairing your hearing by enduring that kind of abusive behavior puts you at a disadvantage in a home defense situation (especially one that awakens you). The flip side is that you should, at least once in your life, fire your carry piece sans protection to at least understand how loud it is. Secondly, this might argue for sub-sonic ammo in your carry piece, such as the old .45 acp. FPSRussia broke his tradition of lack-o-PPE in one of his recent videos, Where he shoots a 40mm Bofors.
Sound does not diminish just because you are outside, it is just not reflected off of a surface as with indoor ranges. Would this mean that every serviceman for the last 100 years or so that has regularly used a rifle ended up with some degree of permanent hearing loss?
On the other hand it’s not unusual for people around here to go to the range and fire more than a hundred rounds weekly.
That professional russian dude is one of my favourite gun youtubers for the simple reason that he is the one thing that the anti-gun lobbyists hate to see: a young goofy guy donning a fake accent using guns in a (mostly) responsible way making fun videos that are very popular across the demographic. I actually told this guy in the comments that he needed hearing protection or he’d be deaf by 30.
Your argument for allowing silencers is that you don’t want to wear hearing protection? It may help you to understand why noise control is so important in this industry, and includes information about permanent hearing loss, temporary deafness and tinnitus. High levels of sound are common, for example in bars, nightclubs, orchestras, theatres and recording studios.
It will also help performers and other workers and employers meet their legal obligations under the Control of Noise at Work Regulations 2005 (the Noise Regulations). These will include musicians and performers, technical staff and others working directly on the entertainment, but also may include staff involved in work activities connected to the entertainment, for example ushers, security, front of house, bar and catering staff etc, depending on their location and length of time spent in the noisy environment. The main responsibility rests with the employer, but everyone should help reduce noise exposure and take a range of simple steps to protect themselves and others from the hazards of loud noise or lengthy exposure to noise at work. These general duties extend to the safeguarding of the health and safety, including the risk of hearing damage, of people who are not your employees, such as contractors and members of the public.
Anyone whose work may create a noise hazard has a responsibility to themselves and to anyone else who may be affected. Unless stated otherwise, readers should assume that values representing average, typical or representative noise levels have been measured using an A-weighting and values representing peak noise with a C-weighting. However, when considering ways to control noise, low-frequency noise needs to be treated differently to high-frequency noise. Generally the potential for hearing to be damaged by noise is related to the noise 'dose' a person receives. When 10 dB is added, the energy is increased ten-fold, while adding 20dB is a hundred-fold increase.
People often experience temporary deafness after leaving a noisy place such as a night club or a rock concert. It may only be when damage caused by noise over years combines with hearing loss due to ageing that people realise how deaf they have become. He often operated stage monitors with a wide range of performers and show formats, including at festivals where he would act as the 'house' engineer - mixing a number of the bands himself and acting as a 'babysitter' to visiting monitor engineers.
Appropriate for selecting suitable hearing protection and designing acoustic control measures.
Noise exposure is not the same as sound level, which is the level of noise measured at a particular moment. The important thing to remember is to always protect your hearing for noise levels above 85 dB and use double protection if levels go over 105dB. Much ado has been made about how you don’t need hearing protection when you’re outdoors because when you’re outside the sound doesn’t have walls to bounce against and therefore isn’t as harmful. While it’s true that enclosed spaces make the noise of gunfire worse, not being outdoors only makes it better in relative terms. James Battey Jr., Director of the National Institute on Deafness and other Communicative Disorders.
The permissible exposure time for loud noises is dramatically reduced for every 3 decibels you go above 85. If you have reached that point then you will be doing damage to your hearing instantaneously.
In his free time he is a volunteer firefighter and enjoys spending time in the mountains with his family. Fifty+ trips to the range each year at a hundred rounds per trip will certainly not do your hearing any good.
One trend I’ve been seeing pick up (albeit very slowly) is the use of elctronic ear pro.
There are cases of performers being unable to carry on their profession because of hearing damage as a consequence of their work. It has been produced by a working group of industry stakeholders with the support of the Health and Safety Executive.

The Regulations specify the minimum requirements for the protection of workers from the risks to their health and safety arising, or likely to arise, from exposure to noise at work.
Employees also have duties under the HSW Act to take care of their own health and safety and that of others whom their work may affect and to co-operate with employers so that they may comply with health and safety legislation.
For example, people cannot usually hear bats communicating at very high frequencies or when whales use very low frequencies.
The terms dB(A) and dB(C) are not used but where noise has been measured using the C-weighting these are referred to as 'peak'. So the division of the A-weighted measurement into its constituent frequencies (frequency analysis) becomes necessary. Common off-hours exposure to high noise levels may include audio and video equipment (personal car stereos, computer speakers, televisions), concerts, clubs and cinemas, sporting events, power tools and noisy hobbies. This may mean their family complains about the television being too loud, they cannot keep up with conversations in a group, or they have trouble using a telephone. Other rarer conditions include hyperacusis (a general intolerance or oversensitivity to everyday sounds) and diplacusis (a difference in the perception of sound by the ears, either in frequency or time). At the end of each simulation the hearing level undamaged by noise for the age of the person is demonstrated.
He eventually plucked up courage to go to his GP, and was diagnosed with noise-induced hearing loss, tinnitus and a condition called diplacusis where the two ears hear a given pitch as two distinct tones - definitely not a good attribute for musical work. Now, as far as controlling where his shots went on his first full auto string, well lets just say that I dont wanna be 4-5 KM downrange of where he was. You can get away with not having it for blank fire (in open spaces) but shooting live rounds you will be required to wear at least plugs.
With all the radio gear we’re being forced to carry, electronic ear pro with radio hookups is becoming more and more valid. This guidance aims to help prevent damage to the hearing of people working in music and entertainment from loud noise, including music. Hearing damage is permanent, irreversible and causes deafness - hearing aids cannot reverse it. With properly implemented measures, the risk from noise in the workplace and the risk of damage to workers' hearing will be reduced. It supplements the general HSE guidance on the Noise Regulations (L108) Controlling noise at work: The Control of Noise at Work Regulations 2005. To account for the way that the human ear responds to sound of various frequencies a frequency weighting, known as the A-weighting, is commonly applied when measuring noise. It is also very important, particularly in music and entertainment, when selecting personal hearing protection, to ensure the correct type for protection from the most damaging frequencies identified during a noise risk assessment.
In general, an employer needs only to consider the work-related noise exposure when deciding what action to take to control risks. It is a sign that if you continue to be exposed to high levels of noise your hearing could be permanently damaged.
Eventually everything becomes muffled and people find it difficult to catch sounds like 't', 'd', and 's', so they confuse similar words.
Danish research among symphony orchestras suggests more than 27% of musicians suffer hearing loss, with 24% suffering from tinnitus, 25% from hyperacusis, 12% from distortion and 5% from diplacusis. Hearing protection should be used for any level over 85 dB and double protection for any level over 105 dB.
Battey states that “Loud noise, such as the 140-decibel blast of a rifle, can irreparably damage the specialized cells of the inner ear—called hair cells—that enable us to hear. My Pel-tor comtacs pick up quiet sounds much better than unaided ears, but keep me from killing my hearing when I pull the trigger.
Performers and other workers in music and entertainment are just as likely to have their hearing permanently damaged as workers in other industries. The exception is when measuring peak noises, where a C-weighting is applied to ensure that proper account is taken of the sound energy in the peak sound. However the employer needs to consider whether risk-control measures need to be adapted in certain situations, for example if it is known that an employee is exposed to noise during other employment. Permanent hearing damage can be caused immediately by sudden, extremely loud, explosive noises such as caused by pyrotechnics. However, there are other studies which give a range of figures from 10-60% for hearing damage among musicians. How many people are going to wear ear protection when confronted with a home intruder situtation? Doing that is as foolish as practicing those martial arts that just consist of getting hit in the gonads over and over, except hearing damage is detrimental. So in some ways I feel that, for me, training without ear protection is sometimes necessary. How many soldiers or marines do you see using ear protection while on patrol,or in a firefight.
I guess what I’m trying to get to is that I believe we all need to be accustomed to the sound of full on, non ear protected,shooting experiences.
