Sudden loud noises

Does the device cancel out sudden loud noises like cars backfiring, gun shots, and doors slamming? This is a feature of most hearing aids and of which I have much appreciation. It would be a welcome addition to the devices features if it is not one already.

Re: Sudden loud noises

Hi CaptainEd,


Thank you for joining the Bose Hear Community and thank you for your interesting question. Let me answer this in three parts.


1. Noise Reduction

Bose Hearphones utilize both active and passive noise reduction technologies. They use a sophisticated proprietary electronics approach to active noise reduction, placing microphones to measure noise both inside and outside the earbud. The electronics system senses the sound in almost any environment and then measures, compares and reacts—instant by instant—to produce an opposing cancellation signal. Patented tip technology from Bose creates a gentle seal at the entrance to the ear canal that enables full-spectrum noise reduction.


2. World Volume

World Volume is the primary controller for Bose Hearphones. Just like the volume setting on the phone controls the loudness of the customer’s music, podcast and phone calls, the World Volume setting controls the loudness of live voices, TV and other environmental sounds. Each customer adjusts the World Volume so that it’s just right for them and for each place they are.


  • Above “0,” the Bose Hearphones will amplify the environment in a special way: Quiet sounds are amplified more than loud sounds so that all sounds can be heard, but none are uncomfortable. This is helpful when the customer needs to hear conversation in acoustically challenging environments.
  • At “0,” the environment will sound as loud as it would if the Bose Hearphones weren’t worn.
  • Below “0,” the Bose Hearphones will reduce sounds in the environment. This is useful so that the customer can escape loud environmental sounds and either focus on their smartphone content or just enjoy the quiet.


The World Volume can be adjusted on the device or using the app. All World Volume settings use Bose Acoustic Noise Cancelling™ technology.


3.  Noise Reduction and World Volume

WIth World Volume at the lowest level, you get the full benefit of both the active and passive noise reduction technologies. As you turn up the World Volume, you hear more of sounds like live voices, TV and other environmental sounds. That can include noises like cars backfiring, gun shots, and doors slamming.


The best way to know if Hearphones will work for you, is to try them in a Bose Store or get them online with a 30-day return policy.
