Function

Intended for study, physics laboratory, physics experiments on: Sound. Sound sources, sound, noise and physiological qualities of sound. What is sound. The frequency of a sound wave, high-pitched sound and low-pitched sound. Auditory intensity, physiological quality associated with the amplitude of sound. Difference between auditory intensity and the intensity of the sound wave. The wave carries only energy. Undesirable sounds, industrial noise. The reverberation of sound. The echo and the minimum distance for a listener to perceive the echo. The reverberation of sound and acoustic comfort. The reverberation time. Stationary waves in an open sound tube, resonance. Identifying the nodes and antinodes of the wave, listening inside the tube. Emitting sound at a frequency and measuring its wavelength. Determining the speed of sound in an open sound tube. Locating hollows and nodes with cork dust. Emitting sound at a frequency, measuring the wavelength, and calculating its speed. Stationary sound waves in a closed tube, resonance. Sound, interference, and the stationary wave in a closed sound tube. Identifying the nodes and antinodes of the wave, listening inside the tube. Emitting sound at a frequency and measuring the wavelength. Determining the speed of sound in a closed acoustic tube. The positions of the nodes and antinodes, indicated by cork powder, etc.
