Hearing test (audiogram)
Daily exposure to a sound level of 80 dB(A) or higher is a good reason for a regular hearing test. By arranging a regular audiogram, you can determine at an early stage whether your hearing decreases.
What does an audiogram measure?
An audiogram is used to record the measurements of different volumes and frequencies of sounds you are able to hear, and helps determine what type of hearing loss you have, if any.
How to recognise hearing loss
In most cases, hearing loss develops gradually. Background noises start to sound a little blurry. Consequently, most people do not notice anything initially. Permanent hearing loss can be identified by one or more of the following symptoms:
- You do no longer hear high tones or soft sounds.
- Having a (phone) conversation in a noisy room costs you a lot of energy
- You hear a ringing, buzzing or whistling sound in your ears.
When is noise harmful?
Sound is observed through the ears; a result of air pressure changes. Noise louder than 80 dB(A) can be harmful. Background noises are usually not above 80 dB(A) if you can still have a conversation with someone in a normal voice. Noise may be harmful if:
- You must speak (very) loudly to understand each other at a normal hearing distance.
- You experience buzzing or a ringing sound in your ears after a day at work.
- You have trouble following a conversation or a TV programme the first few hours after you came home from work.
