Pinniped Hearing in Complex Acoustic Environments
نویسنده
چکیده
Pinnipeds (seals, sea lions, and walruses) are amphibious marine mammals that are susceptible to coastal anthropogenic noise. The long-term goals of this effort are to improve understanding of (1) the sound detection capabilities of several pinniped species, and (2) the effects of noise exposure on the sound detection capabilities of these species. The laboratory and field studies associated with this research will reveal certain aspects of how amphibious mammals receive, perceive, and recognize acoustic information in background noise and will contribute broadly to current knowledge of marine mammal bioacoustics.

Reliability of underwater hearing thresholds in pinnipeds
Repeated measures of low-frequency underwater hearing sensitivity in individuals of three pinniped species tested over 4–7 years are presented. Despite changes in the experience of the subjects and certain testing parameters (e.g., equipment and research personnel), measured underwater hearing thresholds within subjects over relatively long periods of time were quite similar at the frequencies ...

Abstract Background and aims: Occupational noise is a major cause of hearing loss and tinnitus. In the present study, acoustic characteristics of tinnitus were evaluated and their relation with hearing loss and nervousness was studied. Methods: Our study was performed on 56 male workers aged between 40 to 56 years including 28 workers with accompanied hearing loss and tinnitus and a long ...
متن کاملAuditory evoked potential measurement of hearing sensitivity in pinnipeds.
The majority of research on marine mammal hearing sensitivity has focused on the odontocete cetaceans (dolphins and porpoises) who possess morphological and neural adaptations that support sensitive passive hearing and a refined echolocation system. Fewer studies have examined the hearing sensitivity of the amphibious pinnipeds (sea lions, seals, and the walrus) who do not possess a sophisticat...
متن کاملFactors Associated with Vestibular Disorders in Patients with Sensorineural Hearing Loss Due to Acute Acoustic Trauma: A brief report
Background & Aim: Acute acoustic trauma is an important cause of sensorineural hearing loss (SNHL). Determination of the frequency and contributing factors for vestibular disorders is important, therefore, the current study was performed to assess these factors in patients referred to the ears, nose, and throat (ENT) clinic of one of the hospitals in Tehran, Iran, during the years 2017 to 2019....

Acoustic neuromas (AN) are schwann cell-derived tumors that commonly arise from the vestibular portion of the eighth cranial nerve also known as vestibular schwannoma(VS) causes unilateral hearing loss, tinnitus, vertigo and unsteadiness. In many cases, the tumor size may remain unchanged for many years following diagnosis, which is typically made by MRI. In the majority of cases the tumor is s...
