Do we normally hear better by bone or air conduction?

Yes, we normally hear better by bone or air conduction until your doctor takes your Rennie and Weber test, then you hear better by bone conduction. Thus Rennie and Weber’s test checks the type of hearing loss and then confirms whether bone or air conduction is better. You normally hear better within yourself with your ears close. Hearing better with your ears blocked is known as the Occlusion impact.

Bone conduction sound travels faster than air and directly reaches the cochlea. A tuning fork can be used to distinguish neural from mechanical conductive hearing problems. A normal person will hear the tone better by air conduction.

Air and bone conduction

Air conduction hearing occurs through the air near the ear, and it involves the ear canal and eardrum. Bone conduction hearing occurs through vibrations picked up by the ear’s specialized nervous system.

Rinne and Webers test

Rinne and Weber’s tests are used to identify the degree of your hearing loss and type of hearing loss. They help decide if you may have conductive or sensorineural hearing loss. This determination enables a specialist to come with a treatment procedure for your hearing changes.

This is additionally found in the Rinne Test, when a tuning fork is set on somebody’s mastoid bone behind their ear, they can’t hear the sound for long, however, when that same tuning fork is put outside their ear they will hear it longer through air conduction. In the event that they have a conductive hearing loss.

A Rinne test judge hearing loss by comparing air conduction with bone conduction. Air conduction hearing happens through the air close to the ear, and it includes the ear channel and eardrum. Bone conduction hearing happens through vibrations got by the ear’s specific sensory system.

Air conduction Vs Bone Conduction

In the conductive hearing loss, bone conduction is greater than air conduction, because bone conduction bypasses problems in the external or middle ear. In the sensorineural hearing loss, air conduction is greater than bone conduction in both ears (as in normal hearing), however, hearing is decreased in the affected ear

Results

Rinne Test – Normal hearing will show an air conduction time that is twice as long as the bone conduction time. In the conductive hearing loss, bone conduction is heard longer whereas, in the sensorineural hearing loss, air condition is heard longer.

Weber Test – Normal hearing will produce equal sound in both ears. In the conductive hearing loss, air conduction is heard longer whereas, in the sensorineural hearing loss, the bone condition is heard longer.
