Research

In the SENSE lab, with appropriate ethics controls, we have access to many otologic clinical populations, including subjects with middle ear disease (cholesteatoma, conductive hearing loss, TM perforations), Cochlear Implants, Bone Anchored Hearing Aids, tinnitus, acoustic neuroma, asymmetric hearing loss, eustachian tube disorders, hearing aid users, vestibular and balance disorder subjects, inner ear disorders such as Meniere’s Disease or autoimmune inner ear disease, and to intraoperative measurements and sampling if needed.

1. Bone conduction hearing

We are investigating mechanisms for bone conduction hearing. Our research includes:

  • Transcranial attenuation of sound

  • 3D skull vibration patterns and relationship to hearing levels

  • Bone Anchored Hearing aids and performance parameters

  • Novel methods of skull vibration

  • Novel tranducers for bone conduction

  • Live human measurements of hearing level, skull vibration and interactions with air conduction when using bone conduction

2. Multisensory interactions

  • Tactile and auditory feedback mechanisms to improve balance in subjects with bilateral vestibular loss, and other balance disorders

  • Reinforcing speech envelope signals with tactile input to enhance speaker identification and comprehension in competing multi-talker background

  • Saccadic attention in subjects with hearing loss, and improvements after auditory rehabilitation with cochlear implants, hearing reconstructive surgery, or Baha

  • Visual and auditory interactions in subjects with profound hearing loss

3. Novel diagnostic methods for otologic function

  • Eustachian Tube function testing using novel sonotubometry and acoustic transmission tests

  • Middle ear reflectance measures in otologic disease

  • Laser Doppler vibrometry of living eardrums

  • Upwards spread of masking, impact of the stapedius tendon

4.Novel Imaging Methods

  • Novel imaging methods for the outer, middle and inner ear using high frequency (50MHz) ultrasound

  • Novel imaging methods for the ear using OCT (optical coherence tomography)
