Word Recognition Scores (WRS)

Description: The word recognition test measures your ability to both hear and understand validated words (typically a list of 50). The word recognition test will determine how well you understand what you hear when speech is loud enough to hear comfortably. Speech discrimination is measured in percentage.

Wide-Band Middle-Ear Reflectance

Description: This is a test that determines the health and functionality of the middle ear, and its efficiency in transferring sound energy from the eardrum into the inner ear. It is part of the cochlear map assessment, which, in total, takes from 30 to 45 minutes.

Vocal Spectrography

Description: This study is similar to voice-print technology that is used in voice recognition and forensic voice analysis. It allows your physicians to break down voice and speech production and measure the strength and frequency of the sound components called formants. The study takes approximately 15 minutes.

Vocal Fold Imaging

Description: Using optical coherence tomography (OCT), we are able to use infrared light to take images of vocal fold vibratory patterns, as well as the surrounding laryngeal tissue. It is similar to ultrasound, but it provides higher-resolution images. OCT can measure how tissues vibrate in response to sounds and covers the frequency range of 0.2–16 Read more

Virtual Reality Simulation of Vocal Environments

Description: Virtual reality simulation of a variety of environments (conference rooms, classrooms, restaurants, performance venues) is performed to assess vocal function in specific target environments while preserving diagnostic/therapeutic requirements of a quiet setting. This simulation can take one to two hours.

Temporal Resolution via EasyGAP, EasyTMT or EasyFD

Description: These three software packages are quick and easy tests with simple interfaces similar to the SMRT. EasyGAP measures broadband gap detection thresholds EasyTMT measures temporal modulation transfer functions EasyFD measures frequency discrimination of modulated noise

Speech-in-Noise Testing

Description: The speech-in-noise assessment determines your ability to both hear and understand validated words and/or sentences in the presence of background noise. These results will demonstrate how well you understand what you hear when speech is loud enough to hear comfortably in the presence of steady-state noise or multitalker babbling noise. Speech-in-noise discrimination is measured Read more

Speech Reception Threshold (SRT)

Description: The speech reception threshold measures your ability to both hear and understand familiarized words. This measures the softest familiar word that your ear can pick up and comprehend. Normally, the speech recognition test will determine the quietest speech that you can discern at least half of the time.

Spectral Resolution Testing via SMRT

Description: The spectral temporally modulated ripple test is a measure of spectral resolution that has been shown to correlate with speech-in-noise performance for hearing-impaired adults. The test is likely to be sensitive to the ability (or inability) to discriminate spectral shapes, even when listeners have no difficulty detecting frequencies.
