The Hearing Health Dangers of Spin Class

An article published today on Vox investigates the possibility of noise-induced hearing loss from long exposure to loud music in spin classes.

Health reporter Julia Belluz interviewed five spin class instructors who revealed concerns about current or future hearing loss. One of them already received a diagnosis, while another blames the class for the chronic tinnitus she now experiences. The two ASHA-certified audiologists interviewed for the story—Ellen Pfeffer Lafargue and Leisa Lyles-DeLeon—discuss how exposure to sounds above the safe listening levels can harm hearing in the short or long term.

Loud Spin Class Music Could Pose Hearing-Loss Risk

Some Young Adults Appear Unaware of Their Own Noise-Induced Hearing Loss

People with “hidden” hearing loss can ace a standard hearing test but still struggle to hear in a noisy room.

Lyles-DeLeon states in the article that each week she has about  one patient who cites an exercise class as potentially responsible for their noise-induced hearing loss. And Lafarge explains how the inner ear’s 16,000 hair cells get damaged by prolonged or extraordinarily loud sounds. The hair cells often recover, but repeated damage can build up and cause permanent hearing loss or tinnitus.

“When the [hair cells in the] ear have been damaged,” Lafarge says, “the sound that the brain gets is distorted, or the ear can’t detect sound.”

Many spin classes turn up the volume to levels around 100 decibels or more. At those levels, instructors can file complaints with the Occupational Safety and Health Administration, which says exposure to sounds of 100 decibels shouldn’t exceed 2 hours a day and no more than 15 minutes of levels at 115 decibels.

Resources for patients or clients on safe listening:

  • ASHA and the World Hearing Organization created engaging, informative materials for their joint Make LIstening Safe campaign.
  • Free sound level meter apps can also let people know exactly where their favorite exercise class falls on the sound meter scale and if they should wear hearing protection.
