Using powerful microscopy techniques, a research team led by scientists at the National Institute on Deafness and Other Communication Disorders (NIDCD), part of the National Institutes of Health (NIH), has pinpointed in mice the precise cellular location of two proteins known to be important for hearing and balance. The discovery provides additional evidence that the proteins, TMC1 and TMC2, are part of the channel complex that is essential for the inner ear to process sound and the signals that are key to balance.

From National Institute for Deafness and Other Communication Disorders

Returning to school can be an exciting time for children as they reconnect with friends, meet their new teachers, and explore new subjects. As your children settle back into the school day routine, help them become aware of noise levels in their school environment.Talk with your children about noise levels at school and the importance of quiet spaces. Ask them to identify the noisiest and quietest spots they’ve noticed during their school day. Give them examples of places that might be loud (gym, crowded hallways, cafeteria) and quiet (classroom during reading time, art class, library).

With teacher and principal approval, your children can take a decibel meter to school to measure noisy and quiet spaces and share what they find with friends. Discuss the findings with your children and explain the dangers of prolonged or repeated exposure to any noise at or above 85 decibels. Sound meters can be purchased from an electronics store or through websites. Downloadable sound meter apps are also available for most smartphones.

For more information on teaching your tweens about noise levels, go to the Noisy Planet website to read Teachable Moments About Healthy Hearing, and take a look at our Interactive Sound Ruler. You can also post your children’s experiences on our Noisy Planet Facebook page.
