Rhinn tuning fork test11/10/2023 ![]() Sensorineural hearing loss occurs from damage to the delicate hairs in the inner ear and the auditory nerves. Sensorineural hearing loss The parts of the ear affected by Sensorineural hearing loss Here are the different types of hearing loss that bone conduction tests can help identify: For example, if you can’t hear very well via air conduction or only hear specific frequencies at higher decibels, a bone conduction test can help determine the source of the problem. However, the case is different if there are abnormalities in your hearing. That’s because you can perceive sound as it passes naturally through your ear canal without problems. Usually, if the results of the air conduction test are normal, meaning there’s no issue hearing the tones via headphones, then a bone conduction test is no longer needed. What Type of Hearing Loss Does a Bone Conduction Test Check? A computer then records your brain activity on an audiogram.Ī computer records your brain activity on an audiogram.Listen to tones played through the headphones. During the test, you’ll hear tones played through the headphones.Wear headphones and sit (From: YouTube/Backyard Brains) You’ll then wear headphones and sit or lie in a comfortable position.The audiologist will attach one electrode behind each ear and one on your forehead.Īudiologist attaching electrodes.As such, it’s common to put babies to sleep or sedate older children before the test. However, patients need to remain completely still during the test. (From: Youtube/Intrinsic Analytics)ĪBR testing is ideal for infants and young children because it doesn’t require a response gesture like pushing a button. The audiologist records results on an audiogram. The audiologist will then record your results on an audiogram.You’ll press a button with each tone played to indicate that you heard the tone.Each tone will steadily decrease in volume until you can barely hear it. The audiologist will then play a series of tones.Wear headphones and sit in a soundproof booth. ![]() You’ll wear headphones and sit in a soundproof booth.Here’s a rundown of what happens during a PTA exam: This test typically uses headphones and relies on air conduction, but it can also be done through bone conduction using an oscillator. ![]() Pure Tone Audiometry (PTA) involves playing back a series of tones at different frequencies and volume levels. However, for those with sensorineural hearing loss, the tone will sound more audible in the healthy ear.
