Did you know that the human hearing range is significantly lower than a variety of animals on land and at sea? The human ear can hear up to 20k hertz. While the Greater Wax Moth has the most extreme sense of hearing that can reach up to 300,000 kilohertz. These moth’s have evolved ultrasound-sensitive ears as a direct response to avoiding bats, their largest predator. Popular Science. Other impressive animal hearing facts include, owls that have crooked ears so that during flight their left ear picks up sounds from below while the right ear hears sounds from up above. Horses can spin their ears in any direction. Bats as well as dolphins use echolocation, which means emitting ultrasonic sounds and measuring the length of time before the sounds echo back in order to locate prey or predators. In addition, dolphins use their teeth to help with hearing, acting like an antenna to help receive incoming sound. While a human ear consists of three muscles and the three tiniest bones in the body, a cat’s ear is controlled by close to three dozen muscles, which allows them to rotate their ears 180 degrees. Use your hunting dog to outperform in the field as their ears can move independently of one another and the frequency range they can hear is far greater than that of humans. Healthy Hearing Spiders are most sensitive to low-frequency sounds and can “hear” by using tiny hairs on their forelegs. Snakes use their jaw bone to detect vibrations on the ground and in the air. This movement is transferred to the inner ear, which is sent to the brain to be interpreted. Alternatively pigeons have an incredibly low hearing frequency at 0.5 herz. This helps them to hear sound over long distances and to detect storms. Members of the animal kingdom need extensive hearing frequency ranges in order to survive in the wild, hunt and avoid danger.
How can we increase our hearing sophistication to be on par with members of the animal kingdom? In ear hearing devices a can help in many ways. All ESP’s custom in-ear hearing protectors safeguard against the harmful noises that cause hearing damage. Advanced technology in ESP’s Dynamic and Stealth models include auto environmental and volume controls that fine tune sounds to hear what’s important and filters unnecessary disturbances. Advanced compression circuitry and an omnidirectional mic will provide the wearer with complex equipment to rival the hearing of some of the greatest game animals.
