Sound Localization
★Exhibit Content: Popular science on the binaural effect and sound source localization principles ★Interaction: Multi-channel interactive sound localization device ★Operation: Visitors press the "Start" button, a random speaker emits a sound, they judge the sound source position through both ears, press the corresponding numbered button on the console to make a selection, challenge three rounds, and learn the scientific principles of auditory localization. ★Exhibit Description: The exhibit consists of 12 speakers suspended in a ring, a console, and an interactive system. When a random speaker emits sound, visitors judge the sound source direction through the time difference and intensity difference of sound received by both ears, and select the corresponding position via buttons. The exhibit uses gamified interaction to intuitively demonstrate the working mechanism of the binaural effect, allowing visitors to understand how the brain locates sound sources through differences in binaural information, while relating to the application of stereo technology. It is suitable for science popularization displays in science and technology museums, youth activity centers, and acoustics science exhibition areas. ★Scientific Principle: This exhibit is based on the binaural effect and sound source localization principles: The different distances from the sound source to the two ears produce time differences and intensity differences, and the brain analyzes these two differences to determine the sound source direction; The binaural effect is the foundation of stereo technology, creating a sense of space by simulating the differences in sound reaching the two ears; For high-frequency sounds, the human ear also distinguishes elevation through the reflection effect of the pinna, further refining the localization mechanism.

★Exhibit Content: Electromechanical interactive experience for popular science on human auditory characteristics and binaural effect directional discrimination ★Interaction: Listening to sound sources, judging sound emission direction, button answering, indicator light feedback for correct/incorrect human-machine interaction ★Operation: 1. Press the start button, and the 5 speakers on the curved wall emit sound sequentially from left to right, completing the sound source position demonstration. 2. The device enters test mode, randomly driving one speaker to emit sound. 3. Judge the sound source direction by hearing, and press the corresponding numbered button on the console. 4. Observe the red and green indicator lights to check the judgment result, and repeatedly experience the binaural localization pattern. ★Exhibit Description: "Sound Localization" is a curved cabinet popular science exhibit themed on human auditory directional perception, belonging to the acoustics science exhibition area, and is a recommended exhibit by PopsciCat Exhibit Store. The exhibit uses a red-framed curved enclosed cabinet, with 5 speakers evenly arranged on the inner curved wall, and an independent console in front, with 6 function buttons and red and green status indicator lights on the console. The exhibit simulates sound sources from different directions, utilizing the physiological principle that the two ears receive sound with volume differences, time differences, and timbre differences, allowing visitors to personally try to distinguish sound direction by hearing alone, intuitively understand the binaural effect, and recognize the formation mechanism of human stereo hearing. ★Scientific Principle: 1. Binaural effect: When the two ears receive sound, there are time differences, loudness differences, and timbre differences, and the brain relies on these differences to determine the sound source direction. 2. The distance from the sound source to the two ears is different, so the sound waves arrive at the two ears at different times and with different intensities, and the brain constructs spatial hearing based on this to judge the sound emission position. 3. It is difficult to accurately locate a sound source with one ear; only with both ears working together can stereo directional perception be achieved. Stereo and surround sound technologies are all developed based on the binaural effect.
