What is noise-induced hearing loss?
Exposure to hazardous, loud noise results in noise-induced hearing loss (NIHL). It can affect people of all ages and may be temporary or permanent.
The good news is that this type of hearing damage can be prevented by wearing appropriate earplugs.
What causes it?
Loud noise can damage the delicate sensory cells of the inner ear. Risk depends on how loud the noise is and how long you are exposed, whether at work, at concerts, while using power tools or through other loud activities.
What are the symptoms?
- Reduced sensitivity to high-pitched sounds, such as bird chirping
- Speech sounding unclear or distorted
- Tinnitus (ringing or buzzing)
- A sense of ear fullness or pressure
How is it diagnosed and treated?
A hearing test shows whether noise has affected your hearing and how. Hearing aids are the treatment of choice for noise-induced hearing loss in the vast majority of instances, and we can trial options through a hearing aid assessment. For progressive cases, cochlear implants may be recommended as an alternative.
Tinnitus that goes with noise damage can be supported with tinnitus treatment.
How can I protect my hearing?
Fitted custom ear plugs, made from impressions of your ears, offer comfortable hearing protection for work, music, shooting and other noisy activities.
When should I see an audiologist or doctor?
Book a hearing test if you have regular noise exposure or notice muffled speech, ringing or fullness after loud events.
Frequently asked questions
Is noise-induced hearing loss permanent?
It may be temporary or permanent, depending on the noise exposure. If hearing does not return after loud noise, or you notice ongoing symptoms, have your hearing tested so the extent of any damage can be measured and managed.
What are the early signs of noise damage?
Early signs include reduced sensitivity to high-pitched sounds such as birdsong, speech that sounds unclear or distorted, tinnitus, and a feeling of ear fullness or pressure. These can be subtle, so a hearing test is a useful check.
How is noise-induced hearing loss treated?
Hearing aids are the treatment of choice in the vast majority of instances. In progressive cases, cochlear implants may be recommended as an alternative. Your audiologist will discuss what suits your hearing and lifestyle.
Can I prevent noise-induced hearing loss?
Yes. This type of hearing damage can be prevented by wearing earplugs when exposed to loud noise. We make custom ear plugs from impressions of your ears so they fit comfortably and can be worn consistently.
Who is at risk?
It affects people of all ages. Anyone exposed to hazardous, loud noise, at work or in leisure activities, can be affected. If you are regularly around loud noise, regular hearing checks and hearing protection are sensible.
