Question

A string vibrates with a frequency of 10 hz .why can't a person hear the sound wavesoduced by the vibrating string ,no matter how large the amplitude of the waves?

Answer 1

A person cannot hear a 10 Hz frequency because it is an infrasound, below the human hearing range of 20 to 20,000 Hz, despite the amplitude of the sound waves.

Step-by-step explanation:

A person cannot hear the sound waves produced by a string vibrating at a frequency of 10 Hz, regardless of the amplitude, because this frequency falls below the normal human audible range. The human ear can detect sounds in the frequency range of 20 Hz to 20,000 Hz. Frequencies below this range are referred to as infrasound and are typically not heard but may be felt as vibrations. While amplitude affects the loudness of a sound within the audible range, it does not make infrasound frequencies audible to humans. Similarly, sounds with frequencies higher than 20,000 Hz are considered ultrasound and are also beyond our auditory perception.
