Research Facilities
Acoustic Phonetics Lab
The Acoustic Phonetics Laboratory is used for experiments
involving the recording and acoustic analysis of speech
production, in particular the prosodic aspects of speech.
This lab contains an IAC booth, 3 computer workstations
for digital signal processing and data analysis, and recording
equipment. Members of this lab also use the equipment of the
Voice Clinic for research, including the spirometer,
glottograph, oronasal nasality measurement and feedback
system, airflow-air pressure measurement system, endoscopy/stroboscopy,
VisiPitch II, and electromyography.
American Sign Language (ASL) Lab
The ASL Laboratory is used by ASL and interpreting students
to practice signing and interpreting skills. This lab
contains video recording and playback equipment, and
numerous instructional videos.
Audiology Rehabilitation Lab
The Audiology Rehabilitation Laboratory is used for behavioral
experiments in audio-visual speech perception and hearing and
other sensory aids. This lab contains an IAC booth, audiometer,
CD-player, Titmus vision screener, TDT Psychoacoustic System,
two computer workstations, and high resolution video monitors.
Auditory Physiology/Evoked Potential Lab
The Auditory Physiology/Evoked Potential Laboratory is used
for human experiments in evoked potentials and otoacoustic
emissions. This lab contains an IAC booth, Nicolet Spirit
2000 4-channel evoked potential system, and Mimosa Acoustics
otoacoustic emission system.
Group Presentation Lab
The Group Presentation Laboratory is used for multi-subject experiments.
This lab contains 4 workstations for presentation of stimuli using
TDT System 3 equipment and collection of responses using keyboard,
mouse, or button boxes.
Language Lab I
The function of Language Laboratory I is video-recording, including video
editing, and data analysis of quasi-experimental, experimental, and qualitative
research in child and adult language. This lab is acoustically treated to
provide a quiet environment in which to record free-field or to complete
data transcription. This lab contains 4 workstations for video editing
and transcription and computerbased data analyses, digital tape recorders
with wireless microphones, and portable video cameras and tripods.
Language Lab II
Language Laboratory II contains 4 workstations for audio and
video recording and editing, video cameras, digital and analog
tape recorders, and assessment instruments for both child and adult language.
Language Lab III, Language Analysis Lab
Language Laboratory III is designed for language-based data analyses.
A full range of digital audio and video editing equipment is available
to facilitate high quality video production, as well as computer
workstations for the creation and presentation of research materials.
Comprehensive software programs are on hand for language analyses,
reaction time experiments, and a variety of statistical analyses.
Psychoacoustics Laboratory
The Psychoacoustics Laboratory is used for behavioral experiments in
human auditory perception as well as the generation, processing, and
analysis of auditory stimuli. This lab contains an IAC booth; TDT
Psychoacoustic System (includes digital to analog and analog to digital
converters, filters, attenuators, mixers, speakers); 2 computer
workstations for software development, stimulus generation, stimulus
presentation, and recording of responses; filters; signal generators;
oscilloscopes; and sound level meters.
Speech Perception and Production Lab
The Speech Perception & Production Laboratory is used for behavioral experiments
in speech production and speech perception, as well as acoustic and articulatory
analysis of speech. This lab contains an IAC booth, 5 computer workstations for
digital signal processing and data analysis, TDT System 3 stimulus presentation
and recording equipment, and an Aloka SSD-1000 ultrasound imaging workstation.
