How we measure hearing loss

Hearing loss is measured in decibels (dB) by one of our expert Audiologists when you attend your hearing test appointment. Hearing loss is measured as loudness versus pitch of sounds and the results of your hearing test are then plotted on an Audiogram.

Our state of the art audiological testing technology allows our Audiologists to accommodate a range of different hearing tests to help identify the type of hearing loss you may have. We will talk to you in detail about the hearing test  and what you need to do as well as discussing the outcome of your hearing test so that you can feel confident in the health of your ears and your hearing ability so that you can regain the joy of hearing.

To understand the type of hearing loss you may be experiencing, hearing is measured using earphones (which measure air conduction). By placing a small vibrator on your head (which largely bypasses the eardrum and middle ear and measures the sound waves that pass directly to the cochlea in the inner ear) this measures the overall efficiency of your hearing.

With the earphones, you can expect to hear tones of different frequencies, testing one ear at a time. The intensity of each tone is varied to find the lowest level that you can hear sounds, which is then used as the threshold for that tone. It is unusual for your hearing threshold to be the same or similar for different frequencies - typically there is a greater hearing loss for high frequency tones. Equally, hearing loss can be different in each ear.

Hearing loss is typically broken down into degrees of hearing loss detailed below:

Mild hearing loss

20-40 dB - Your loved one cannot hear soft sounds and they struggle to understand speech in noisy places. 

Moderate hearing loss

41-70 dB - You cannot hear moderate sounds and have difficulty understanding speech when there is background noise. 

Severe hearing loss

71-95 dB - You have to ask people to raise their voices and group conversations are extremely difficult. 

Profound hearing loss

More than 95dB - You can only hear some very loud sounds and communication is impossible without hearing aids.

Our expert Audiologists take the time to listen and understand where your hearing challenges are now and your expectations for the future. Life is for listening and we’ll ensure that you feel happy and confident in interacting with the world around you.

After their hearing test, your Audiologist will plot the results on a graph and use the measurements to advise you of their degree of hearing loss.
