The speed of sound in the air is 340m / s. The length of the sound wave in the air for the lowest male voice reaches 4.3m. Determine the frequency of vibration of this voice.
Initial data: υ (speed of sound in air) = 340 m / s; λ (sound wavelength of the lowest male voice) = 4.3 m.
The vibration frequency of the lowest male voice is determined by the formula: ν = υ / λ.
Let’s calculate: ν = 340 / 4.3 = 79 Hz.
Answer: The vibration frequency of the lowest male voice is 79 Hz.
