Archived Webinar: Music and Hearing Aids with Marshall Chasin – Aired April 17, 2024 at 1pm ET

February 21st, 2024

DATE: Wednesday, April 17, 2024 – 1 PM ET

SPEAKER: Marshall Chasin, Au.D., reg. CASLPO, Marshall Chasin and Associates

Abstract:

Music and speech have some differences which include spectral shape, intensity and “crest factors”. Most modern digital hearing aids cannot handle the more intense inputs that are characteristic of music. Four new technologies and four clinical strategies will be provided to optimize hearing aids for music as well as for speech. These technologies are designed to circumvent some problems associated with the analog-to-digital conversion process- a major weak point with many modern hearing aids. Audio files will be showing the problems of the hearing aid not being able to handle the higher level signals associated with music, as well as demonstrating the difficulties with frequency compression for music.

Learning Objectives:

After attending this seminar, the participant should be able to:

  • Select software programming that is optimized for music
  • Explain the engineering limitations of most modern hearing aids for music
  • Identify some simple clinical strategies to improve a hearing aid for music
