Abstract
Zvuk je longitudinalni val kojeg ljudi i životinje opažaju osjetilom sluha. Frekvencije titranja zvuka koje čovjek može čuti nalaze se u intervalu od 20 Hz do 20 tisuća Hz. Zvuk frekvencije iznad ljudskog čujnog područja naziva se ultrazvuk, a ispod infrazvuk. Neke životinje koriste ultrazvuk za snalaženje u prostoru ili komunikaciju. Čovjek je također našao načine kako primijeniti ultrazvuk. U ovom radu opisane su vrste valova, kako ljudsko uho reagira na zvuk, zatim nastanak i primjene ultrazvuka te primjer ultrazvučnog uređaja kućne izrade.

Parallel abstract (English)
Sound is a longitudinal wave which animals and humans notice with sense of hearing. Frequencies of sound vibration that human ear can hear are located in interval from 20 Hz to 20 000 Hz. Sound of frequencies above human hearing range is called ultrasound and below infrasound. Some animals use ultrasound to move around or to communicate. People have also found ways to use ultrasound. Various kinds of waves are described in this paper as well as how human ear reacts to sound, also how ultrasound was made and applied and example of a home made ultrasound device.
