Hint: A human ear is only sensitive to a certain range of sonic vibrations because then only it can catch every minute pressure difference in the air.
Complete Step by step solution
The range of frequency between $20{\text{ Hz}}$ to $20,000{\text{ Hz}}$ is the range that a human ear can easily detect and hence sound waves with frequency of this range are called as Audible or Sonic vibrations. This is because a human ear is sensitive to every minute pressure difference in the air if they are in this frequency range.
Sound waves of frequency above $20,000{\text{ Hz}}$ are known as Ultrasonic vibrations. These vibrations are very useful in medical and metal industries.
Sound waves of frequency below $20{\text{ Hz}}$ are known as Infrasonic vibrations. Such types of vibrations are produced during earthquakes, thunder and volcanoes. Humans can’t hear in this range but some animals like whales and elephants can hear this.
Hence the answer is true
Note: Range from $20{\text{ Hz}}$ to $20,000{\text{ Hz}}$ is the Audible or Sonic vibrations range. Frequencies above $20,000{\text{ Hz}}$are known as Ultra sonic and that below $20{\text{ Hz}}$ are known as Infrasonic vibrations.
