Evaluation of a Remote Microphone System with Tri-Microphone Beamformer.
J Am Acad Audiol
January 2020
Hearts for Hearing Foundation, Oklahoma City, OK.
Background: Children with hearing loss often experience difficulty understanding speech in noisy and reverberant classrooms. Traditional remote microphone use, in which the teacher wears a remote microphone that captures her speech and wirelessly delivers it to radio receivers coupled to a child's hearing aids, is often ineffective for small-group listening and learning activities. A potential solution is to place a remote microphone in the middle of the desk used for small-group learning situations to capture the speech of the peers around the desk and wirelessly deliver the speech to the child's hearing aids.

Functional hearing in the classroom: assistive listening devices for students with hearing impairment in a mainstream school setting.
Int J Audiol
December 2016
a Department of Audiology and Speech Pathology , The University of Melbourne, Melbourne , VIC , Australia.
Objective: To assess the benefit of assistive listening devices (ALDs) for students with hearing impairment in mainstream schools.
Design: Speech recognition (CNC words) in background noise was assessed in a typical classroom. Participants underwent testing using four device configurations: (1) HA(s)/CI(s) alone, (2) soundfield amplification, (3) remote microphone (Roger Pen) on desk and (4) remote microphone at the loudspeaker.
A screening approach for classroom acoustics using web-based listening tests and subjective ratings.
PLoS One
May 2016
Occupational and Environmental Medicine, The Sahlgrenska Academy at the University of Gothenburg, Gothenburg, Sweden.
Background: Perception of speech is crucial in school where speech is the main mode of communication. The aim of the study was to evaluate whether a web based approach including listening tests and questionnaires could be used as a screening tool for poor classroom acoustics. The prime focus was the relation between pupils' comprehension of speech, the classroom acoustics and their description of the acoustic qualities of the classroom.
