Hearing Capabilities of Animals — Can They Really Hear Better than Humans? While it may seem animals can hear better than humans because they can hear sounds we can’t hear, their ability to hear is not better than ours. What differentiates hearing in animals vs. humans is what an animal needs to hear in order to survive. Animal hearing capabilities also depends on the placement, size and shape of their ears. For example, animals with large pinnas (the visible parts of the ear) such as bats and elephants are better equipped to detect vibrations since big pinnas are more effective at funneling vibrations to the eardrum. Also, animals with heavy ear bones cannot pick up high-frequency vibrations but are superior at hearing lower frequencies. Hearing Range of Humans Frequency is the number of vibrations produced each second by an object emitting sound or movement. Each sound carries different frequencies that are measured as a hertz. A single vibration per second is equal to one hertz. Sounds with low frequencies have low pitches (your heartbeat, for example). High frequency sounds have high pitches (dog whistles). Humans cannot detect sounds occurring at all frequencies, but neither can animals. Audiologists report that a healthy young adult human presents a range of hearing between 20 and 20,000 hertz. By middle age, your ability to hear high frequency sounds may have deteriorated to between 12,000 and 14,000 hertz. Facts About Human Hearing and Hearing Loss The ear is a fascinating part of the body, but its ability to detect noises can be easily damaged. Here are some facts about hearing and hearing loss: Humans have around 25,000 hair cells responsible for sending vibrations to the eardrum. Lengthy exposure to sounds over 90 decibels can permanently damage hair cells. If a hair cell dies, it won’t grow back. Police officers, construction workers, factory workers, musicians and military personnel are at a high risk for suffering significant hearing loss as they age. Nearly 30 percent of people over 65 experience some level of hearing loss they may or may not be aware of. You can permanently damage your hearing if you don’t wear ear protection and are exposed even for a short time to a shotgun blast, concert, explosion or other extremely loud noise.

Facts About Animal Hearing Although dolphins are among the top animal sound detectors, they do not have ears. Instead, dolphins rely on ear drums located outside their bodies. In addition, dolphins use sonar “hearing,” or echolocation, to enhance their already superior hearing abilities. Bats also utilize echolocation to determine location and size of things in the dark. In fact, bats can find small insects 30 feet away from them in pitch darkness using echolocation. Elephants hear frequencies 25 times lower than humans are capable of hearing. They also depend on their feet and trunk to “hear” using specialized receptors for detecting low frequency vibrations. Cats can hear higher frequencies than humans and dogs. Over two dozen ear muscles allow cats to rotate their cone-shaped ears 180 degrees in different positions. That’s why no matter how quietly you open that can of cat food, your cat will hear it.
