For the sake of testing air conduction
, they use earphones inserted into the ear rather than headphones that fit around the ear.
The averaged of the air conduction
(AC) and bone conduction (BC) thresholds of right and left ears, obtained for the frequencies 250, 500Hz, and 1, 2, and 4KHz are shown in Fig.
Keller, blinded during infancy and ``possessing neither bone nor air conduction
in either ear,'' is fascinating.
For the first time, Ponto Pro Power brings the advanced innovative features that have revolutionized the field of air conduction
hearing devices to people with severe hearing loss who cannot benefit from traditional hearing solutions," said Jes Olsen, Oticon Medical General Manager.
(250 to 6,000 Hz), bone conduction (500 to 4,000 Hz), and speech recognition threshold (SRT) and speech discrimination scores were determined in both ears of participants via a TDH-39 earphone.
PTA was performed for both air conduction
and bone conduction using Arphi Diagnostic Audiometer 2001 model for 250Hz to 4kHz.
Pure tone audiometry (PTA) threshold for each ear was determined at 250Hz, 500Hz, 1KHz, 2kHz, 4KHz and 8KHz by air conduction
Tomatis's contention is that osseous conduction is the major route of sound conduction to the inner ear, not air conduction
The website provides the same air conduction
test that is given in most hearing clinics.
We compared the mean pre- and postoperative PTAs for air conduction
, bone conduction, and air-bone gap (ABG) at 0.
5,Disposable drapes,Transducer for air conduction
testing headphone (along with the cable) Model: TDH50
and Bone conduction thresholds for the frequencies from 250KHZ to 16K KHZ were recorded.

The post-operative air conduction
was within 25 dB in 73.
Cholesteatomas often present with fetid otorrhea, but in this case, progressive hearing loss secondary to poor air conduction
was the only presenting symptom.
