We are sound specialists and our work needs to be heard to be experienced…but do you actually know how sound and hearing works?

An object emitting energy in the form of a vibration causes sound. Areas of high and low pressure move outwards creating a form of a longitudinal wave (a wave which vibrates in the direction of travel). The amplitude (volume) and frequency (pitch) of the sound wave depends on what the source is and the amount of energy supplied outwards.

But how do we sense and process these sound waves?

That’s the job of our ears. The ear is an extremely clever organ, consisting of a collection of tiny bones, tubes and membranes (namely the eardrum), which process the sound and send it to the brain. The funnel-like shape of the ear is effective at collecting the sound wave and filtering it through the ear passage, where it causes vibrations of the eardrum. The signal is gradually converted into an electrical signal by the rest of the ear, and this is then sent to the brain.

Many species use sound, not only to communicate but also to assess the nature of their surroundings, dependent on the way they interact with emitted sound waves.

And now you understand a little bit better the science behind sound and hearing. Simple enough isn’t it?
