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. Reposition the tuning fork, pressing the base against a bony structure near the ear ( Position B).įor people with conductive hearing loss, the tone will typically sound louder in the compromised ear.Keep holding for 2-3 seconds.(From: Youtube/Oxford Medical Education) Hold this position for 2-3 seconds to let yourself listen to the tone.Hold the tuning fork perpendicular to the ear canal. Hold the tuning fork 1 cm away and perpendicular to the ear canal ( Position A). (From: Youtube/ Oxford Medical Education) Sound the tuning fork by striking it against your knee or flicking the prongs between your fingers.įlick the tuning fork prongs between your fingers.Here’s a step-by-step guide for performing these tests: How to perform the Rinne test On the other hand, the Weber component only uses bone conduction.īy analyzing which position delivers the loudest sound, audiologists can determine whether you have conductive or sensorineural hearing loss. The Rinne component uses air and bone conduction and involves placing a tuning fork in different positions near the ear. These tests have two parts, as the name suggests. The 512 Hz tuning fork is ideal for these tests because its tone takes a long time to decay. As such, they’re commonly called Tuning Fork Tests. The Rinne and Weber tests use tuning forks to evaluate hearing loss. Let’s take a closer look at each type and how they work: In addition to headphones, other bone conduction tests also employ devices like tuning forks and electrodes. However, if there’s a significant gap, you may potentially have conductive or mixed hearing loss. Essentially, if there’s no gap, this could indicate the presence of sensorineural hearing loss. It all boils down to how notable the gap is between the air and bone conduction results. The audiologist then analyzes the air-bone gap to gauge the degree and type of hearing loss present. On the other hand, bone conduction results use “ ” for left ear results. For air conduction, right and left ear results use an “ O” and “ X,” respectively. However, readings that go beyond 20 dB indicate hearing loss.īoth air and bone conduction results are recorded using different symbols. Normal hearing means you can hear all frequencies within the 0-20 dB range.
