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.
There are many things that can cause damage to the auditory system, but the most common is noise damage. Please visit the NIH’s Interactive sound ruler for examples of various types of sounds and their hazard levels.
Musicians work in a high decibel environment in which hearing loss, tinnitus, hyper-sensitivity to sound and sound distortion can result.  Traditional earplugs are not a good choice for the professional musician, as they reduce sound by muffling low-to-mid-range frequencies, which change the frequency spectrum of what they are hearing. Hunting requires the ability to hear very soft sounds, while still having a need for protecting the ear from the peak noise levels of a gun blast. The diagram below illustrates the noise levels and corresponding lengths of exposure at which damage to the auditory system can occur. Scientists have long known that the brain not only receives signals from the ears, but can also talk back to them.
Frisina and colleagues published evidence in 2002 that the dimmer switch effectiveness declines with age. Balance differences between ears may also contribute to the lack of ability to hear in background noise.
Being aware of noise levels in certain environments may allow you to make better decisions as to where and how to conduct meetings etc. If you suspect you have a hearing problem an indicator may be increased reluctance to conduct conversations in noisy environments. The standard hearing aid microphone is sensitive to sounds from all directions (omni-directional). Directional microphones can reduce the level of noise coming from the side or behind the users making conversations easier with people directly in front of you.
The SNR (Single Number Rating) indicates an insulation value averaged over the relevant frequencies.
The HML values indicate how high sound reduction in three frequency ranges, H (high), M (middle) and N (low) is. Acoustic shock is an injury caused to telephone headset users by exposure to abrupt and unexpected high pitched tones (HPT), 'shrieks' or other noises (loud or soft) that may occur in telephone networks.Another cause of acoustic injury can be using telephone headsets where you are constantly listening to your callers at a loud level.
Summary Statement: Provides a basic understanding of the nature of noise exposure in construction and details on how to set up a hearing conservation program to minimize hearing loss.


We all know somebody affected by hearing loss, as nearly 1 in 5 Australians live with the condition. Quality of life can be significantly compromised for people with hearing loss and their families. In contradiction to many people's understanding, hearing loss is rarely similar to the effect of turning down the volume on a stereo.
If you feel that your hearing is not what it used to be, or are concerned that a loved one may be experiencing hearing loss - take a couple of minutes to do the online hearing tests provided here.
However, conductive loss accounts for only 10% of all hearing losses, and they range from mild to moderate in severity. When volume is sufficiently increased, clarity and understanding are usually intact for someone with a conductive hearing loss. Hearing loss that originates in the inner ear is referred to as sensorineural hearing loss or - in laymen's terms, nerve deafness. While the overall volume of sound may be reduced, the clarity of sounds or voices is also affected.
An example of a mixed hearing loss may be someone with inner ear damage due to exposure to noise in their workplace over many years, who also currently has an infection that has led to a fluid build up in the middle ear. While the ageing process is a major contributor to hearing loss, it is certainly not a condition reserved for the later stages of life. Not surprisingly, given the impact of noise, males are considerably more likely to have hearing loss than women - including being twice as likely to have a moderate to severe hearing loss. This graph shown here illustrates the time it takes to cause permanent damage to your hearing when you're exposed to different levels of sound. Nerves have different sensitivities to deformation of the sensory hair cells within the cochlea.

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. Custom musicians earplugs are available that can protect the musician’s ears from loud sounds without distorting what they hear.
Loud, sudden noises (gunfire, industrial noises, woodworking, motorcycles, loud music, motorized lawn equipment, noisy hobbies and other noises louder than 90 db) are more damaging to hearing than regular and extended exposure to loud sounds over a period of time.
Ear muffs or ear-plugs should be worn when activities such as mowing the lawn or using a chainsaw are undertaken. And when there's too much noise, this dimmer-switch brain circuitry tells the ears to reduce their flow of signals to the brain.
The drop-off showed up in middle-aged people (ages 38 to 52) and was even worse in people past age 62. The only way to cope is through a great deal of concentration and a fair amount of guesswork. Aids that incorporate directional microphones are designed to pick up sounds coming from in front of the listener better than they pick up sounds coming from other directions.
Suppression algorithms are used to reduce volume (gain) in frequency bands where the noise level is estimated to exceed the speech level.
This level is known as your average listening level.This injury is not just linked to faulty equipment. The extent of the hearing loss varies too, from a mild to a severe hearing loss where loud safety signals may not be heard.
The good news is that conductive hearing loss can often be medically treated, and in many cases, hearing can be completely restored.
Other symptoms may also be present, such as ear pain, drainage from the ears, or a feeling of pressure or a blockage. In more than 95% of cases involving sensorineural hearing loss, hearing aids or cochlear implants are the recommended course of treatment.
People with sensorineural hearing loss will often hear people speaking, but can't always understand all the words, even when the volume is adequate. Studies have shown that exposure to noise is thought to be a contributing factor in around 37% of cases of the condition - and interestingly, around 50% of Australians with hearing loss are still of traditional working age (i.e.


This is illustrated through mandatory provision of ear protection on work sites and within factories. A sound that has high frequencies of vibration will excite receptor cells near the opening of the cochlea, while a sound mostly containing low frequencies will stimulate cells at the end of the cochlea. 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.
There are also a variety of in ear monitors that will enhance the music experience whether you are a serious musician or just a music aficionado. Not only can they choose from custom or over-the-counter earplugs or earmuffs, they can also choose protection devices that provide amplification while reducing the sounds of gunfire down to a safe level.
Venues such as nightclubs or entertainment venues that have excessively loud noise should be avoided or ear protection used. This may be one reason people with hearing loss tend to withdraw - or find they get tired easily in noisy environments.
It is not limited to any particular telephone or headset type, or any particular telecommunications network or equipment. More commonly it is manifested as a difficulty with word understanding, particularly in the presence of background noise. This can lead to conversations being difficult to follow - particularly in noisy environments where competing background noise 'scrambles' speech and conversations. Nevertheless, every day millions of Australians are exposing themselves to noise levels that will surely lead to long-term damage to their hearing, including the use of personal stereo systems.
Commonly, over time the high frequency hair cell receptors receive more movement by the incoming pressure waves of the fluid inside the cochlea - so are more prone to long term damage than the low frequency hair cell receptors, which are more protected further up the cochlea.
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 protectors not properly fitted to the wearer’s ears do not effectively prevent damaging noises from penetrating the ear canal. If you have to shout to make yourself heard by someone standing within 1 to 1.5 meters of you, the noise level is considered excessive and it will exacerbate your tinnitus. Not unsurprisingly, being able to follow conversations is the single biggest reason that people seek our help. 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. Headsets exacerbate the problem as they take longer to remove than handsets.The Effects of Acoustic ShockStress and anxiety can heighten the effects of acoustic shock.
