air conduction

Air conduction results in isolation, give little information regarding the type of hearing loss.

A traveling wave is created similar to that created by air conduction signals.

Hearing care professionals agree that for these types of problems Baha is a more effective solution than air conduction devices.

A high-power conventional air conduction hearing aid fits deeply into the patient's deaf ear.

Standard reference zero for the calibration of pure tone air conduction audiometers"

If the conductive part of the hearing loss is more than 30-35 dB, an air conduction device could have problems overcoming this gap.

If the hearing loss is significant an air conduction aid may have difficulty to overcome the dysfunction of the eardrum and middle ear bones.

In sensorineural hearing loss the ability to sense the tuning fork by both bone and air conduction is equally diminished.

Audiometric data Table 2contains the grand averaged pure tone air conduction thresholds for 190 patients who returned follow-up questionnaires.

Spectacle aids come in two forms, bone conduction spectacles and air conduction spectacles.

The Rinne test, which tests air conduction vs. bone conduction is negative (abnormal result).

If they are not able to hear the tuning fork after mastoid test, it means that their bone conduction is greater than their air conduction.

Both the 'artificial ear' and 'acoustic reference coupler' are designed for the purpose of calibrating (air conduction) audiometer outputs.

When the thresholds obtained via air conduction are examined alongside those achieved with bone conduction, the configuration of the hearing loss can be determined.

Conductive hearing loss is confirmed in the weaker ear if bone conduction is greater than air conduction and the Weber test lateralizes to that side.

It compares perception of sounds transmitted by air conduction to those transmitted by bone conduction through the mastoid.

Von Bekesy is credited with the discovery that at the level of the cochlea, phase shifted bone-conduction signals cancel out air conduction signals.

For infants, Wave V latencies for bone-conduction clicks are shorter than the air conduction clicks.

A similar calibration procedure to the above is used for air conduction audiometry, using either an Artificial Ear or Acoustic Reference Coupler.

Irritation in the external ear canal can be due to inflammation or eczema and makes it impossible or very uncomfortable to use a conventional air conduction aid.

In this case, that parameter is if air conduction (AC) is better than bone conduction (BC).

Air conduction spectacles Unlike the bone conduction spectacles the sound is transmitted via hearing aids which are attached to the arm or arms of the spectacles.

A conventional air conduction aid with a mold placed in the ear canal opening is often impossible to wear due to the drainage - and may even provoke drainage.

Audiology and vestibular tests should be concurrently evaluated using air conduction and bone conduction threshold testing to assess for sensorineural versus conduction hearing loss.

The Rinne test, which tests air conduction vs. bone conduction is positive (normal), though both bone and air conduction are reduced equally.
