While occupations like construction, law enforcement and the military are often associated with noise-induced hearing loss, teachers face similar risks due to the high noise levels in classrooms. Below, we’ll cover how loud sounds impact hearing, examine noise levels in classrooms and offer tips to help teachers protect their hearing.
How Loud Sounds Damage Hearing
Inside the inner ear, tiny hair cells called stereocilia play a crucial role in hearing. These delicate cells convert sound waves into electrical signals that travel through the auditory nerve to the brain, where they are interpreted as sound.
When exposed to high decibel sounds, these cells can become damaged or even destroyed. Unfortunately, once damaged, stereocilia do not regenerate, leading to permanent sensorineural hearing loss.
Classroom Noise Levels: What Teachers Should Know
Noise levels in classrooms can reach harmful levels, leading to potential hearing issues among teachers. Consider these findings:
- High noise reports: In a recent study, 94% of teachers surveyed reported that their classrooms were uncomfortably loud.
- Hearing-related complaints: Around 65% of surveyed teachers reported hearing issues, including symptoms like tinnitus.
- Unsafe sound levels: Classroom noise can exceed 85 decibels (dB), the maximum safe threshold for an eight-hour workday.
Tips for Preventing Hearing Loss for Teachers
Teachers can take proactive steps to protect their hearing in noisy classroom environments. Here are some practical tips:
Enhance Classroom Acoustics
Classroom noise is often amplified by hard surfaces like tile floors, windows, and bare walls, which cause sound to reverberate. Adding soft, absorbent materials can reduce noise levels:
- Hang curtains over windows.
- Use rugs on floors.
- Add cork boards, felt wall decorations, and other soft surfaces.
- Incorporate tablecloths or soft mats on desks and workstations.
Use Musician’s Earplugs
Musician’s earplugs, designed to reduce harmful noise while preserving sound quality, aren’t just for music teachers. They allow teachers to hear clearly while lowering the volume of loud sounds. These earplugs can be especially helpful in louder classrooms or during events like assemblies.
- Collaborate with colleagues
- Experienced teachers in Arlington and other school districts may have useful strategies for managing classroom noise. Colleagues may offer tips on acoustics, classroom management, or noise-reduction techniques to make the environment more hearing-friendly.
