Abstract
Ultrazvuk je mehanički val, odnosno zvuk frekvencije izvan spektra čujnosti ljudskog uha, dakle iznad 20 000 Hz. U prirodi se ultrazvuk pojavljuje kao zvučni val, ali može se i proizvesti ultrazvučnim generatorima, odnosno pretvaračima drugih oblika energije u energiju ultrazvučnih valova. Tako se ultrazvuk može dobiti pomoću inverznog piezoelektričnog efekta, te pomoću magnetostrikcije. Pri prolasku ultrazvuka kroz neki materijal dolazi do refleksije, refrakcije, transmisije, difrakcije i apsorpcije ultrazvučnog vala. Ultrazvuk se primjenjuje u mnogim tehničkim granama. Primjene su različite, mnogobrojne i od velikog značaja za modernu tehnologiju. U ovom završnom radu opisan je fenomen zvuka, te osnovna fizikalna svojstva zvuka. Rad je posvećen ultrazvuku, izvorima ultrazvuka, te načinima rasprostiranja ultrazvučnih valova. Također se bavi njegovim raznolikim primjenama u medicini, navigaciji, defektoskopiji itd.
Abstract (english)
Ultrasound is a mechanical wave, sound frequencies beyond the range of audibility of the human ear, above 20 000 Hz. In nature ultrasound appears as a sound wave, but it can also be produced by ultrasonic generators. They convert other forms of energy into energy of ultrasound waves. Ultrasound can be obtained by using the inverse piezoelectric effect and magnetostriction. Passage of ultrasound through a material leads to reflection, refraction, transmission, diffraction and absorption of ultrasonic waves. Ultrasound is used in many technical fields. Applications of ultrasound are various, numerous and of great importance to modern technology. This bachelor's thesis describes the phenomenon of sound, and basic physical properties of sound. This work is dedicated to ultrasound, ultrasound sources, and methods of propagation of ultrasonic waves. It also deals with its various applications in medicine, navigation, defectoscopy, etc.
