A sound with a short envelope, usually with a less sharp attack than a click. Pulse is also called an impulse. With frequencies below about 20Hz, individual oscillations may be heard or sensed as slow pulses of pressure variation without pitch characteristics.

Son possédant une enveloppe courte et, habituellement, avec une attaque moins raide qu'un clic. Les oscillations d'une fréquence inférieure à 20Hz peuvent êtres entendues comme des impulsions lentes de variation de pression sans hauteur caractéristique.

Suono con un inviluppo molto corto, e un attacco meno veloce di un click. Le oscillazioni con frequenza inferiore a 20Hz possono essere percepite come impulsi lenti di variazone di pressione senza altezza caratteristica (Source - Barry Truax - Handbook for Acoustic Ecology CD-ROM Edition.

Emissione istantanea di potenza. Una sequenza di impulsi (o treno di impulsi) viene usata nella produzione sintetica del parlato come § funzione di eccitazione.

Un sonido con una envolvente breve, usualmente con un ataque menos abrupto que un clic (click). El pulso también recibe el nombre de impulso. Las oscilaciones individuales por debajo de los 20 Hz pueden ser "oídas" o percibidas como pulsos lentos de variación de presión sin características de altura.
