Protect your hearing before it's too late.

SMART ALERTS

• Daily noise dose alert when you reach your safe exposure limit
• Based on NIOSH hearing safety guidelines

SESSION HISTORY

WHO IS IT FOR?
HearSafe is for anyone who cares about their hearing — musicians, concert-goers, parents, workers in loud environments, or anyone who wants to know the sound levels around them.

HEARING SAFETY STANDARDS
HearSafe uses the NIOSH (National Institute for Occupational Safety and Health) safe exposure formula. At 85 dB, safe exposure is 8 hours. Every 3 dB increase halves that time.

Take control of your hearing health today.
