Vibrotactile stimulation of the larynx to treat unexplained chronic cough
This is a study of adults with unexplained chronic cough between 18-80 years old. This study is trying to determine whether a noninvasive vibrotactile stimulation device can help reduce cough symptoms.
• adults aged 18-80
• more than 8 weeks of non-productive cough
• chest x-ray or chest CT negative (collected as part of routine clinical care); no time limit on imaging (if available)
• clinical impression that untreated or inadequately treated gastroesophageal, pulmonary, and/or sinus or nasal issue is not the reason for the cough
• able to read and speak English
• current smoker or quit less than 3 months ago
• infectious cause for cough (e.g., TB, pertussis, COVID)
• history of known or suspected aspiration pneumonia
• recent intubation/neck surgery (within 8 weeks)
• neuromuscular impairment that may affect cough/laryngeal sensation and/or function (e.g., multiple system atrophy, Parkinson, CVA)
• untreated carotid artery disease
• electronic implants (e.g., pacemaker)
• specific medications (study staff will discuss)
• anticipate use of new medications to treat the cough during the period of the study
• currently having speech therapy for cough
• BMI > 40 (for transmission of VTS through soft tissue)
• allergy to adhesives
• drug/alcohol dependency or abuse
• pregnant
• without regular access to wifi and internet
Listening effort in people with hearing impairment
The purpose of this research is to understand the effort needed to understand speech if hearing is impaired. Listening effort is higher in people with hearing impairment and has wide-ranging negative consequences across many aspects of a person’s life. The goal of this project is to explore factors that make listening effortful, with special focus on the need to repair perceptual mistakes by relying on context.
• There are two categories of participants: either people with cochlear implant (one or two cochlear implants) or people with normal hearing in both ears. All participants must be 40-75 years old.
• non native English speakers
Development of objective measures for multisensory effects on hearing
Paired sound and electrical stimulation can alter how the brain encodes sounds and the perception of sounds, as shown in emerging evidence from animal studies. The aim of this study is to develop measures for paired stimulation that can be used reliably. These measures assess the following aspects of hearing: basic hearing sensitivity and cochlear health, perception of loudness and pitch, and perception of speech and music/complex sounds. This will lead to a greater understanding in the hearing science community about how multisensory stimulation can alter activity in the auditory system and sound perception, which may lead to new techniques for improving hearing disorders.
• not users of hearing aids or implanted devices
• normal hearing or hearing-impaired, with or without tinnitus
• users of hearing aids or implanted devices
Measurement of Upper Aerodigestive Tract Pressures During Phonation
The purpose of this pilot research study is to test whether a tool called “High-Resolution Manometry” can diagnose laryngeal dystonia (also known as spasmodic dysphonia) and measure how well treatment works. High-Resolution Manometry measures pressures from a small catheter that is passed from your nose into your throat. We believe that pressures in the throat might be different for people with laryngeal dystonia than for people without laryngeal dystonia, or with other types of voice disorders. If we can diagnose laryngeal dystonia shortly after symptoms start, we can get patients the treatment they need sooner.

Assessments of sound perception and brain activation in response to paired sound and electrical stimulation of surface ear regions
We are investigating how paired non-invasive electrical stimulation of surface body regions and sound changes sound perception and tinnitus. Body stimulation regions include: external ear/behind the ear, shoulder, neck, forearm, hand, and upper arm. We aim to better understand the optimal conditions of this paired stimulation, which opens opportunities for applying this method to improving hearing loss or tinnitus. We are studying three groups of people: those with normal hearing, those with mild to moderate hearing loss, and those with tinnitus.
• normal hearing or hearing loss with or without tinnitus
• not users of Cochlear Implant or hearing aids
