Dimensions of the acoustic reflex as measured in a background of noise

This study examines whether background noise, presented at 10 dB below its reflex threshold, affects the acoustic reflex (AR) response for pure tones presented subsequent to the onset of the noise.

Evaluating the directional effects of acoustic horn style hearing aids using the QuickSIN procedure

This paper evaluates the directional effects of two hearing devices – an antique London Dome horn style device and a constructed Cupped Hand. The comparisons were made using the Quick SIN (Speech in Noise) adaptive test which measures signal-to-noise ratio loss.

Auditory and audio-visual reception of words in noise by observers with normal and impaired hearing

This dissertation examines auditory perception and audio-visual reception in noise for both hearing-impaired and normal hearing persons, with a goal of determining some of the noise conditions under which amplified acoustic cues for speech can be beneficial to hearing-impaired persons.

Strial capillary permeability following noise exposure in mice

A study of strial capillary permeability using fluorescent microspheres and immunohistochemistry in mice that do or do not exhibit a reduction in endocochlear potential following a single, intense noise exposure.

Development of curriculum in noise awareness

This paper presents a curriculum in noise awareness developed for use in the second and fourth grades, to teach children about the harmful effects of elevated noise levels.

Speech intelligibility in noise-induced hearing loss: effects of high-frequency compensation

This dissertation examines the frequency response that results in the maximum level of speech intelligibility for persons with noise-induced hearing loss.

Toward an acoustic vowel metric: listener validation

This paper examines objective measures of speech production, specifically vowels. The relationship between the listener's perception of sections of the vowels with their perception of the entire vocalic utterance was examined.

Noise exposure in the operating room

This paper discusses a study done to determine noise levels in operating rooms

A comparison of physical measurements of pure-tones, third-octave bands of noise and third-octave bands of speech to subjective judgments of audibility threshold, MCL and UCL for three normally hearing listeners

This study investigates the relation between physical measurements of pure-tones, third-octave bands of noise and third-octave bands of speech and subjective judgments of auditory threshold, most-comfortable listening level (MCL) and uncomfortable-listening level (UCL) for three normally hearing listeners.

Noise levels and hearing conservation in a water treatment facility

This paper describes a study assessing the sound levels and noise exposures of a municipal water treatment plant to determine the level of employee noise exposure dosages and to make any necessary recommendations regarding reducing the risk of noise induced hearing loss in employees.

Acoustic phonetics applied to auditory training and the teaching of speech to the hearing impaired

This paper is a review of acoustic phonetics as applied to auditory training for hearing impaired children.

Role of alpha synuclein in noise induced hearing loss

The recent discovery of the contribution of alpha synuclein in the auditory system prompted further investigation of its functional role. Auditory brainstem response (ABR) and gap detection testing were completed on wild-type and transgenic M83 mice to assess the role of alpha synuclein in noise-induced hearing loss and central auditory function.

The effectiveness of noise cancellation headphones for hearing impaired listeners

This paper discusses the use of noise cancellation headphones for hearing aid users to reduce background noise in order to improve speech discrimination.

Bone-conducted tones masked by air-conducted noise

This paper presents a study designed to develop and evaluate a method for obtaining monaural thresholds for bone-conducted signals masked by air-conducted noises.

Reaction-times of hearing-impaired children to acoustic stimuli of different sensation levels

This paper discusses a study to determine the relation between sensation level and response time to acoustic stimuli.
