None ! Some animals such as bats, use ultra-sonic sound to locate prey, and 'see' in the dark.
Supersonic waves are waves that can travel faster than normal sound waves.
Supersonic waves are used in supersonic flights. They are also used in body scanning and used to detect faults in metal.
That's a sonic boom. Sound waves are never supersonic in themselves, objects can be supersonic ... which causes a pressure wave (which moves at "sonic" speeds) and which can be heard (firing a gun will do it).

the bats do not produce supersonic sounds.they produce ultrasonic sounds.Thats the reason we cant hear them
Ultrasonic refers to frequencies greater than those that can be heard (usually frequencies above 20 kHz). Supersonic refers to velocities faster than the speed of sound (in the medium under consideration).
a sound wave transmitted at a frequency greater than 20,000 per second, or beyond the normal hearing range of humans. The specific wavelength is equal to the velocity divided by the frequency. this wave is generated from tranducers, tranducers converts the electrical energy into mechanical energy(wave), i.e ultrasonic wave.supersonic waves are those wave whose velocity are greater than the sound wave. Supersonic waves are generated by high explosives.
At this rate, we will reach supersonic speeds within seconds.
Supersonic flow is characterized by speeds faster than the speed of sound. It is often used in applications such as supersonic aircraft, missiles, and high-speed wind tunnels. Supersonic flow can create shock waves and high temperatures, making it challenging to control and design for.
Vapor cones are important in the study of supersonic flight because they indicate the formation of shock waves around an object moving faster than the speed of sound. These shock waves can affect the aerodynamics and performance of the aircraft, making it crucial for engineers to understand and account for them in the design of supersonic vehicles.
It is an oxymoron, a self-contradiction, in that sound must travel at the speed of sound (which does vary by the medium or material). Supersonic means "faster than sound."You might, however, describe vibrations as being supersonic, meaning that they are traveling faster than sound would in air.
