Home alarm sirens can be silent, or they can be downright deafening. The BodyGuardz® Portable 5-in-1 Emergency Hub includes a loud home alarm siren that’s designed to make you easy to find in any situation—whether it’s a family member in another part of the house or a first responder who’s come to the rescue. But it’s also good to know our alarm won’t cause any substantive damage to your hearing. In an emergency, you want to feel as prepared as possible. That includes knowing exactly how to use and what to expect from the loud 90-decibel home alarm siren in our Emergency Hub.
How Loud is 90 Decibels?
As a general reference for what 90 decibels sound like, it’s about the same loudness as a gas-powered lawn mower or subway train. These sounds are loud enough that a normal conversation is difficult-to-impossible to have. Keep in mind that decibels, like earthquakes, are measured on a logarithmic scale, so there’s a big difference from 80 to 90 decibels and from 90 to 100 decibels. We’ve carefully crafted an emergency alert device that is plenty loud—but not too loud.
How Long Can You Listen to 90 Decibels Before Causing Hearing Damage?
You can generally listen to 90 decibels for anywhere between 20 minutes (CDC) and 2.5 hours a day (NIOSH) without being concerned about hearing damage. Exceeding these limits in an emergency situation isn’t likely to cause any significant hearing damage, and the risk can be further mitigated by covering your ears. In many emergency situations, you will also want to periodically turn the alarm off and listen for someone to respond.
How Far Does 90 Decibels Travel?
This is a tricky one to answer due to a dozen different variables including ambient noise, atmospheric attenuation, and individual hearing ability. In some situations, our 90-decibel alarm can be heard 1-2 km away. In an emergency situation, you may be surrounded by significant noise and sound barriers. Still, the alarm should be heard throughout the home and surrounding area in most cases. Plus, our 5-in-1 includes alert notifications that get sent directly to your emergency contact list.
