Due to the wide range of signal properties and media they propagate through, specialized equipment may be required instead of the usual microphone, such as a hydrophone (for underwater sounds), detectors of ultrasound (very high-frequency sounds) or infrasound (very low-frequency sounds), or a laser vibrometer (substrate-borne vibrational signals).

Debido al amplio rango de las propiedades y medios en los que se propaga, se requiere equipo especializado como: un hidrófono (para sonidos submarinos), un ultrasonido (para detectar sonidos de altas frecuencias) o un vibrómetro (para señales sustrato-aire).
