Hearing conservation Program
Music and entertainment industry
Music and entertainment sectors are defined in the National Code for Noise management as all workplaces where:
a) live music is played or
b) recorded music is played in a restaurant, bar or nightclub.
Our program consists of five steps:
- Education and training
- Sound exposure surveys
- Risk analysis
- Audiometric assessment
- Provision of hearing protection devices
We achieve this by:
- Providing information, instructions and training to employers about their responsibility in noise regulation. Making sure the legal limits are not exceeded.
- Assessing risks to employees from noise at the workplace
- Taking action to reduce the noise exposure that produced those risks.
- Provide employees with hearing protections devices if the noise exposure cannot be reduced enough by using other means.
- Regularly monitor employees hearing status for any changes.
Effect of loud music on hearing- how loud is too loud?
How long is too long? The two are related. The louder the sound the shorter the time before damage can occur.
Anyone who is exposed to loud sound (exceeding 85dBA) is at risk of damaging his or her hearing. This includes:
- Night club/hotel employees and patrons
- Sound crews/stage managers
- Recording engineers
- Users of personal listening devices
- Dancer and performers
The Effect of Sound on Ears
The human ear is much like any other body part too much use and it may be damaged. The ear takes about 16 hours to “reset”. After attending a rock concert or a loud music session. You may notice reduced hearing or tinnitus (ringing in the ears). And if your hearing was assessed immediately after the concert, one would find a temporary hearing loss. After 16 hours however, your hearing should return to its baseline level. If the exposure continues damage to the hearing system can result irreversible damage (nerve deafness).
Symptoms of Hearing Damage
Depending on the severity, people with noise induced hearing loss typically report varying degrees of:
- Difficulty following conversation in group
- Difficulty following conversation in competing background noise
- Lack of clarity of speech in1 on 1 listening situations
- Distortion of music quality
- Reduced tolerance to loud sounds
When should hearing protection be used?
Noise regulation law makes the use of personal hearing protection compulsory for employees working with designated areas (hearing protection Zones). The employer must provide personal hearing protection to any employees who requested it.
Types of hearing protection available
- Pre-moulded ear-plugs. These are generic fit ear plugs shaped for average users’ ear canal.
- Custom moulded ear plugs. These are professionally fitted to users’ ear. These provide even attenuation of frequencies better sound quality and very little occlusion effect.
