How we measure hearing loss
Hearing loss is measured in decibels (dB) by one of our expert Audiologists when your loved one attends their hearing test appointment. Hearing loss is measured as loudness versus pitch of sounds and the results of their 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 your loved one may have. We will talk to them in detail about the hearing test and what they need to do as well as discussing the outcome of their hearing test so that they can feel confident in the health of their ears and their hearing ability so that they can regain the joy of hearing.
To understand the type of hearing loss they may be experiencing, hearing is measured using earphones (which measure air conduction). By placing a small vibrator on their 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 their hearing.
With the earphones, they 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 they can hear sounds, which is then used as the threshold for that tone. It is unusual for their 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 - Your loved one cannot hear moderate sounds and have difficulty understanding speech when there is background noise.
Severe hearing loss
71-95 dB - Your loved one has to ask people to raise their voices and group conversations are extremely difficult.
Profound hearing loss
More than 95dB - Your loved one 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 their hearing challenges are now and their expectations for the future. Life is for listening and we’ll ensure that your loved one feels happy and confident in interacting with the world around them.
After their hearing test, the Hearing Aid Audiologist will plot the results on a graph and use the measurements to advise them of their degree of hearing loss.
