Mild hearing loss : 20 to 40 dB higher than normal.The results of the hearing test are an indication for the degrees of hearing loss: This is also used for calculating how much amplification will be applied by the hearing aid when the loss is present. Threshold establishment determines what tones and what intensity can be heard. When recording the softest level heard when wearing the bone conductor, the “threshold” is known as bone conduction.When recording the softest level heard when wearing the headphones, the “threshold” is known as air conduction.
In doing so, the audiologist can record these levels on a graph – the audiogram. You’ll be instructed to indicate when you can first detect the tone at a specific frequency, usually by pressing a response button. The audiometer allows the audiologist to vary the frequency (the pitch) and intensity (the loudness) of tones. You’ll listen for tones which are presented via specially constructed electronic equipment, known as audiometer, an electric instrument created specifically for hearing tests. This test requires you to wear specially calibrated headphones and subsequently a specially calibrated bone conductor (which vibrates sounds through the skull). The first and perhaps most fundamental test is pure tone audiometry. The hearing assessment uses a battery of tests to ascertain your hearing abilities. This is critical, as a hearing aid is tuned to make the sounds that cannot be heard louder, rather than just making all sounds louder. By testing your hearing at different frequencies, your audiologist can ascertain which sounds are heard and which sounds are not. Just as an example: A face-to-face conversation is about 65 decibels.Īn audiogram can be read from left to right for frequency and from up to down for the intensity in decibels. On the left side, you can see the units for loudness, which is measured in decibels. The higher that number, the higher is the pitch of the sound. The numbers on the top ranking from 125 to 8000, are indicators for sounds frequencies. It is, simply put, a graph that shows the softest sounds you can hear at different frequencies and pitches. But how do you read the audiogram charts that display the result of your test? In today’s post, we’ll help you to interpret your audiogram results! What is an Audiogram?Īn audiogram measures your hearing ability and the degree of your hearing loss. A diagnostic hearing test is usually the first step on your way to better hearing health. Many things can cause hearing loss, and we will most likely experience some degree of decreased hearing with age. Our hearing is a complex sense that most of us take for granted until we lose it.
