For audiologists

A new generation of inexpensive, 

non-invasive hearing technology,

born of new results in neuroscience

What is Buzz? How does it work? Who is it for? Why should I recommend it to my patients?

  • Neosensory builds inexpensive, non-invasive technology to enhance sound perception through the skin
  • Buzz is a complementary device to amplification (e.g. hearing aids, cochlear implants)
  • This is a research-backed device that provides clinically-meaningful benefits (sound awareness, improvement in speech discrimination, and tinnitus-reduction). See research papers below.
  • Algorithms use over 29,000 different patterns based on sound intensity and pitch
  • Our studies in bimodal stimulation demonstrate clinically-significant reductions in tinnitus severity for 87% of users
  • Adjustable frequency response to customize experience
  • Developed by Stanford neuroscientist Dr. David Eagleman with Dr. Scott Novich
