China Wholesale Hearing Threshold Pricelist – LMEC-16 Apparatus of Sound Velocity Measurement & Ultrasonic Ranging – Labor Detail:

The propagation speed of sound wave is an important physical quantity. In ultrasonic ranging, positioning, liquid velocity measurement, material elastic modulus measurement, gas temperature instantaneous change measurement, will involve the sound speed physical quantity. The transmission and reception of ultrasound is also one of the important means of anti-theft, monitoring and medical diagnosis. This instrument can measure the speed of sound propagation in the air and the wavelength of sound wave in the air, and add the experimental content of ultrasonic ranging, so that students can master the basic principles and experimental methods of wave theory.

Experiments

1. Measure the velocity of sound wave propagating in the air by the method of resonant interference.

2. Measure the velocity of sound wave propagating in the air by the method of phase comparison.

3. Measure the velocity of sound wave propagating in the air by the method of time difference.

4. Measure the distance of a barrier board by the method of reflection.
