Question

Help me ultra sound vs infrasound

Answer 1

Answer:

Differnces:

Infrasound is sound that is below the lower limit of human hearing below 20 Hz

ultrasound is above the upper limit of human hearing, above 20,000 Hz.

Commons:While ultrasound reflects strongly from even small objects and can be highly directional for both large and small animals, infrasound has neither of these charac- teristics. ... Thus, ultrasound is effective only over short distances while infrasound can be used for communication over very long ranges
