FAQ:

Q: What are ear defenders used for?

A: Open plan offices are very fashionable at the moment, but they can make it much harder for you to concentrate and get things done. Ear defenders can help you block out your co-workers’ distracting conversations and help you focus on the task at hand.

Q: How do ear defenders protect your ears?

A: Ear muffs or defenders have cups lined with sound-deadening material . The protection usually comes from acoustic foam which absorbs sound waves by increasing air resistance, thus reducing the amplitude of the waves.

Q: Do you wear ear defenders?

A: If you work in an industry where high noise levels are common or if you just do a lot of DIY, you probably wear ear defenders regularly . Loud noises can pose a significant risk to your hearing, so ear defenders exist to protect your hearing as you work.

Q: What is the best shooting hearing protection?

A: Electronic ear protection is generally considered to be the best ear protection for shooting overall. It works by amplifying ambient noises using microphones and speakers so you can still hear what is going on. It then cuts off the amplification or lowers the sound level whenever there is a gunshot.
