超声波是一种机械波。机械波的频段很宽，从10-4~1014Hz。以频率划分依次为次声波、声波和超声波三大类。20Hz以下的波动为次声波；20Hz~20kHz的波动为声波；20kHz以上的波动为超声波。
用于治疗和清洗的频率范围在20~2000kHz。高强度聚焦超声质量仪器采用1MHz左右的频率。用于临床诊断的频率范围在1~60MHz。其中心脏及腹部成像的频率在2-6MHz范围；浅表器官成像的频率范围在7~12MHz；皮肤及血管内成像的频率范围在10~40MHz，生物显微镜成像的频率高达40~60MHz；目前诊断最常用的超声频率是2~12MHz。检查成人心脏一般选2~4MHz，小儿心脏3~5MHz，腹部产科3~5MHz，外周血管浅表器官6~12MHz，血管内20~40MHz，眼科超声显微镜40~100MHz。6MHz以上工作频率的探头称为高频探头。
