Ears That Hear from Afar

Acoustics

★Exhibit Content: Sound focusing, pinna effect ★Interaction: Model interaction ★Operation: Sit on the seat with both ears facing the earpieces, adjust the direction of the curved surface, and listen to the collected sound. ★Exhibit Description: The exhibit consists of a seat, a rotating bracket, a sound-collecting dish, and earpieces. A set of listening devices is installed. Sound waves are reflected by the large concave sound-collecting dish and converge at the focal point of the curved surface. Earpieces are installed at the focal point to transmit the sound to the ears. ★Scientific Principle: Sound focusing refers to the phenomenon where sound waves, when encountering a concave surface, are reflected and concentrated together, forming sound focusing. This phenomenon is similar to light focusing, causing sound energy to be particularly concentrated in a certain area, making the sound in that area particularly loud while the sound in other areas becomes relatively weak. This phenomenon also occurs in daily life. For example, in a concert hall, if there is a large concave wall, sound focusing may occur, causing the sound in certain areas to be particularly noisy and affecting the audience's listening experience. The pinna effect refers to the role of the human ear's pinna in collecting sound waves. The pinna not only collects sound waves but also helps determine the direction of the sound source. When sounds from different directions are reflected and diffracted by the pinna, the human ear can perceive subtle differences in sound. In addition, by changing the shape of the pinna (such as twisting the outer ear, pressing the ear flaps together, or pulling up the earlobe), the sound heard also changes. This is a specific manifestation of the pinna effect.
