Normative wideband acoustic immittance patterns for middle ear evaluation in dogs.

The objective of this study was to investigate the clinical use of wideband acoustic immittance (WAI) reflectance for middle ear assessment in dogs. Otoscopy and brainstem auditory evoked response testing was performed on all dogs prior to the WAI assessment. Following calibration, dogs were comfortably restrained while the probe was placed into the ear canal to obtain recordings.

Tinnitus loudness tracking: a "type V Békésy" pattern does not exist for pseudotinnitus.

Background: Evaluation tools are lacking for the identification of patients exhibiting pseudotinnitus. It was hypothesized that tinnitus loudness traces might show a separation between continuous and pulsed tones for participants exhibiting pseudotinnitus, that is, the "type V" pattern shown for threshold tracking among participants exhibiting pseudohypacusis. It was further hypothesized that tinnitus loudness tracking might reveal unreliable tinnitus loudness matches among participants exhibiting pseudotinnitus due to their lack of an internal tinnitus standard.

AuD students' perceptions and influences regarding careers in independent practice.

Purpose: Independent practice (IP) may be important for the financial stability and autonomy of audiology. The authors sought to identify variables that affect doctor of audiology (AuD) students’ decisions to enter IP or another practice setting.

Method: The authors sent a survey link electronically to 1,430 members of the Student Academy of Audiology; 300 returned completed surveys.

Assessment of objective pulsatile tinnitus in a patient with syringohydromyelia.

We examined a 38-year-old male with syringohydromyelia and concomitant symptoms suggestive of intracranial hypertension including unilateral low-frequency sensorineural hearing loss and objective pulsatile tinnitus. The tinnitus was heard by the authors (through a hearing aid stethoscope tube), measured objectively (with a probe microphone), measured subjectively (as minimum masking levels and with fixed frequency Bekesy), and altered by changes in ear canal pressure (subjectively reported and measured objectively with a probe microphone). The audiologic symptoms were likely associated with elevated cerebrospinal fluid pressure that traveled to the cochlea through the cochlear aqueduct.

Hearing handicap among adult residents of an urban homeless shelter.

This retrospective study was undertaken to identify the prevalence of hearing loss in the homeless population and its implications for vocational rehabilitation. Audiometric threshold data for adult residents of an urban homeless shelter were collected and reported. Subjects with hearing loss were identified and defined by their binaural high-frequency pure tone average (B-HFPTA).
