![]() The vibrations travel from the eardrum via ossicles to the cochlea (a fluid-filled organ), causing surface waves that strike hair cells. Different sounds make different vibrations that affect how the eardrum moves. ![]() When we hear a sound, we are experiencing sound waves funneling into the ear canal and moving the eardrum, much like a drum head vibrates when struck. The mechanics of hearing demonstrate some of the mechanics of sound energy. Let’s learn more about the intriguing world of sound, including sound energy examples. But it’s a beginning and the science behind it is developing. Admittedly, that’s a long way from generating enough electricity to power a home or an entire city. In fact, a group of young high-school students figured out how to produce enough electricity with sound energy to turn on a light bulb. For example, microphones and speakers are examples of sound becoming electrical energy. Though the science of turning sound energy into electricity is still emerging, it has been done. So what is sound energy, exactly? Sound energy is turning sound into electricity. Regardless, sound energy travels and depending on the sound source and the intensity, sound can sometimes be considered a pollutant. Sound sources may be pleasant or unpleasant to the human ear, depending on loudness, different pitches, types of sound, sound source, and sound intensity. ![]() There are many different types of sound ranging from the audible to the inaudible. From the roar of traffic to the sound of musical instruments, humans make a lot of noise. Can we use sound energy to turn noise into forms of energy? Sounds crazy, but we discover different types of energy all the time - especially when it comes to renewables - and sound energy is just another kind.Īround the world, it’s hard to find somewhere that noise is not part of the landscape.
