Pseudoauditory air conduction thresholds in the deaf
International Journal of Audiology, 1977Pure-tone air conduction thresholds, as well as speech detection thresholds, were obtained from both ears of 10 profoundly deaf individuals before and after the administration of a local anesthetic in two conditions: under earphones, and while wearing a conventional-type hearing aid.

Audiometric Calibration: Air Conduction
Seminars in Hearing, 2014The main goal of this article is to discuss the calibration of air-conducted signals delivered by an audiometer via an earphone or a loudspeaker. The common types of earphones used in hearing testing are described and the importance of calibrating these transducers is discussed.

Estimation of the air-bone gap using interleaved air-conduction and bone-conduction ABR [PDF]
, 2019 There is a need for monitoring of both the standard and extended frequency range during middle ear surgery. This project set out to provide a system that could receive an estimation of the air-bone gap using interleaved air conduction (AC) and bone conduction (BC) auditory brain-stem response (ABR).

Round window membrane motion with air conduction and bone conduction stimulation
Hearing Research, 2004The vibration patterns of the round window (RW) membrane in human cadaver temporal bone specimens were assessed by measurements of the velocity of reflective targets placed on the RW membrane with an approximate spacing of 0.2 mm. The velocity was measured in the frequency range 0.1-10 kHz by a laser Doppler vibrometer in four specimens with air ...

Air and Bone Conduction Brain Stem Responses in Adults and Infants
International Journal of Audiology, 1983 Air and bone conduction brain stem responses were recorded in 20 adults and 20 infants (16-20 months postconceptional age) with normal hearing. The stimuli were administered using a shielded TDH-39 headphone and a standard B-70A vibrator.

Air conduction and bone conduction in aging mice
The Journal of the Acoustical Society of America, 2014Umbo velocity and Auditory Brainstem Response (ABR) measurements in aged mice suggest that there are functional changes in both the inner ear and middle ear for frequencies from 5 to 13 kHz (Doan et al., 1996). In this work, we use a combination of air conduction (AC) and bone conduction (BC) stimulation to better quantify the middle ear contribution ...

Is cartilage conduction classified into air or bone conduction?
The Laryngoscope, 2013Objectives/HypothesisThe aim of this study was to establish the sound transmission characteristics of cartilage conduction proposed by Hosoi (2004), which is available by a vibration signal delivered to the aural cartilage from a transducer.Study DesignExperimental study.MethodEight volunteers with normal hearing participated. Thresholds at frequencies
