Don't Overprotect your Hearing

Overprotecting your hearing doesn't make you safer - it actually can cause danger.

You could be overprotecting without even knowing it. When earplugs first came out in the 1970s, hazardous noise levels were much louder than they actually are today, therefore requiring attenuations of protection. However, today's environment has new machines, facilities, and processes combined with engineering and administrative controls that have caused noise pollution to decrease considerably. Even modern hearing devices have been updated with wider ranges of protective options to better accommodate various occupational noise hazards. 


Yet, many people are still using too-high, static-rated protection. Is this you? If so, what does this mean for you in the workplace? 


The Consequences of Overprotection

 If you overprotect, that means there is a very small amount of noise you can hear... which isn't necessarily good. With overprotecting, you might not be able to hear potential harm nearby. According to HexArmor, the target level of sound to hear safely is between 70-80 decibels (dB), with safe speech perception at 65 dB. If you wear earplugs that overprotects at a higher attenuation than what's needed for your work environment, you're more prone to take your protection out of your ears to hear your coworker talking to you - which is very problematic, especially in the long term - even if you take them out for five minutes. 

The BIGGEST hazard that you can face with overprotecting is not being able to hear the sound of danger coming your way. Failure to hear warning sounds/signs - such as an alarm system, machinery failing, or shouting could put you in real danger. Finding earplug options that offer the correct protection for your application or environments makes a huge difference - ultimately keeping you safer and highly protected on the job.

Hearing Protection


How much protection is needed?
  1. It is important that you understand the noise levels in and around your workplace. This can be calculated via a sound audit conducted by a safety professional. 
  2. Understanding the proper fit (both earplug style and decibel level) and proper wear time can help combat overprotection.
