With a noise reduction of 32dB, these ear muffs provide exceptional noise cancellation, reducing the impact of loud sounds and helping to create a calmer environment for dogs. This cancellation is not perfect—speech isn’t very clear if the headset cancellation gets turned on by a gunshot close by—but is helpful combined with the passive control provided. Active sound cancellation works by using one or more microphones to sample incoming sound, an electronic processor to compute a sound wave that is 180 degrees out of phase with it, and one or more speakers to play this computed “anti-sound,” all before the original sound wave reaches the subject’s ear or a target area in a room.

PLA is a ecofriendly, biodegradable plastic derived from plant fibers, which is a renewable organic resources. You can find a statue of Greyfriars Bobby near the south (main) entrance to Greyfriars Kirkyard in Edinburgh Scotland.The reason that this is a troubling claim is that the frequency range of human speech, 80–8,000 Hz, completely encloses the range where ANC works best.

We live above a kindergarten and Lucky is terrified of children so the noise from downstairs is making her very anxious.

Consider the dog's breed, as well as designs that cater to small dogs or large dogs, so that your furry friend can avoid loud sounds. This will be our first 4th with our nervous rescue and wanting to avoid more stress for her as much as possible. Originally designed as protective gear for dogs in the military, RexSpecs provide protection for both ears and eyes. There is not a consumer product on the market that can protect your dog from the sudden, low-frequency sounds of thunder and fireworks or make him feel significantly better about them.

It can never become too loud for the dog as the headphones have a limiter that remains within safe canine hearing levels. The exterior is made of lightweight plastic, ensuring that the ear muffs do not add unnecessary weight or pressure to the dog's head.

Our Noise Cancelling Headphones help dogs sleep through fireworks, thunderstorms, and other loud noises. So being able to compute and output the new sound wave during the time sound travels about an inch from the outside to the inside of the headphone is a challenge. We put a limiter on the volume to protect out dogs hearing, and not introduce damaging volumes to our dogs.
