Deaf people are perceived by hearing people as living in a silent world. Yet, silence cannot exist without sound, so if sound is not heard, can there be silence? From a linguistic point of view silence is the absence of, or intermission in, communication. Silence can be communicative or noncommunicative. Thus, silence must exist in sign languages as well. Sign languages are based on visual perception and production through movement and sight. Silence must, therefore, be visually perceptible; and, if there is such a thing as visual silence, how does it look? The paper will analyse the topic of silence from a Deaf perspective. The main aspects to be explored are the perception and evaluation of acoustic noise and silence by Deaf people; the conceptualisation of silence in visual languages, such as sign languages; the qualities of visual silence; the meaning of silence as absence of communication (particularly between hearing and Deaf people); social rules for silence; and silencing strategies.

This paper presents information on the reliability of distortion product otoacoustic emissions in children with profound sensorineural hearing losses.

This paper presents a study investigating the relationship between tympanometry measures of the middle ear and Distortion Product Otoacoustic Emissions (DPOAE) screening, suggesting that using a combination of the two methods in pediatricians’ offices would result in fewer inappropriate referrals for comprehensive hearing evaluations.

This paper studies the test-retest reliability of distortion product otoacoustic emissions (DPOAE) in newborns in a neonatal intensive care unit.

This paper describes a project which set up a system to measure distortion product otoacoustic emissions (DPOAEs) in the Sprague Dawley rat and to conduct a pilot study to measure the development of DPOAEs as a function of age.

This paper discusses a study done of neonates to determine the differences between ABR and DPOE for hearing screening.

This paper discusses the effect of noise exposure on high school aged boys' hearing levels and how to measure the effects.

This paper studies the relationship between hearing sensitivity and the presence of otoacoustic emissions by examining the variability of same ear emissions in a group of normal-hearing subjects.
Resumo:
This paper examines distortion product otoacoustic emissions (DPOAEs) used to test peripheral auditory function, and how noise level in the ear affects the detectability of DPOAEs. The study examines the clinical feasibility of different time averages at different frequencies on the noise floor.

This paper is a review of a study on distortion product emissions in normal hearing chinchillas.

This paper discusses the distortion-product otoacoustic emissions (DPOAE) of chinchillas when exposed to noise.
