[MobilePRwire] – Safety of electronic ear protectors designed for shooting probed as new hearing safety chart compares electronic ear protectors costing hundreds of dollars against a new iPhone powered hearing protection app.
Audio app pioneers Essency, publish controversial hearing safety chart that compares the safety of electronic ear defenders designed for shooting against ‘GunSonics!’, a newly released hearing protection app that sets a new standard in hearing safety for gun users.
The recently published electronic ear defender comparison chart at www.gunsonics.com compares the reaction time of leading electronic ear defenders, as specified by their manufacturers, against the GunSonics! app and shows in graphic terms how gunshot noise forms an ear-damaging peak, before the electronic ear defenders can react.
The chart shows that the GunSonics! hearing protection app running on an iPhone, outperforms expensive ear defenders to stifle gunshot blasts before they can cause any damage.
Electronic ear defenders sold for shooting use, have a microphone on one or both ear cups that feed an internal amplifier, which then transmits ambient sounds to the user with speakers inside the ear cups. When a gun is fired the amplifier temporarily shuts down and hearing protection is dependent on the speed of shut down and the passive attenuation of the ear cups.
The key factor is whether electronic ear defenders can act fast enough to prevent harmful sound pressure peaks from reaching the user’s ears, via the internal electronics.
The fastest electronic ear defender on the market has a manufacturer’s specified reaction time of 1.5 milliseconds (thousandths of a second). The GunSonics! hearing safety chart shows that gunshots blasts reach ear damaging levels within 2 milliseconds and are millions of times louder than the safe listening levels recommended by The National Institute for Occupational Safety and Health (NIOSH).
The sound pressure level (SPL) of gunfire, varies from 144dB for a 0.22 caliber pistol to 170dB for larger revolvers or rifles. Exposure to 1.5ms of an amplified gunshot can lead to non-reversible, noise induced hearing loss, tinnitus or even instant deafness.
NIOSH states that exposure to one gunshot at 140 dB SPL constitutes 100% of a person’s daily allowable noise exposure. The Occupational Safety and Health Administration’s (OSHA) permissible exposure limit for impulsive noise is also 140 dB SPL.
Essency co-founder, Alex Georgiou said: “The immense processing power of the iPhone blows away the tech used in electronic ear protectors. The hearing safety chart on www.gunsonics.com shows that the GunSonics! App does not amplify any part of a gunshot blast and when used with high NRR passive ear protectors, GunSonics! provides the safest method to date to hear, talk and shoot at a fraction of the cost of electronic ear defenders.”
The GunSonics! App works with passive ear protectors, worn over the top of Apple standard issue headsets connected to an iPhone or iPod Touch. This allows shooters to choose passive ear protectors with a higher NRR (Noise Reduction Rating) for maximum protection.
GunSonics!® for iPhone will be officially released on 7 November 2013 on Apple’s iTunes App Store, priced at $9.99 USD.
GunSonics!® for Android will follow shortly.
