Alarme d'incendie que l'on retrouve généralement dans les collectivités (Lycées, collèges, centres, etc.). Same sound as #0268 and #2250, but longer. Difficult to loop. UCS Category: ALRMElec. Duration: 00:39.
Pink noise or 1/ƒ noise (sometimes also called flicker noise) is a signal or process with a frequency spectrum such that the power spectral density (energy or power per Hz) is inversely proportional to the frequency: en.wikipedia.org/wiki/Pink_noise. UCS Category: TEST. Duration: 00:19.
Several beeps of an active sonar. This is a low frequency sonar (long range but low definition). It is a sine wave of 1040 Hz frequency easy to put in loop. In reality, a military submarine usually has passive sonar, more sonar info: en.wikipedia.org/wiki/Sonar. UCS Category: BOATSub. Duration: 00:21.
Beeps an electrocardiogram during cardiac arrest. This sound was made on computer. It is a square wave of frequency 475 Hz. UCS Category: BEEPMed. Duration: 00:23.
An electrocardiogram beep when the heart beats at 60 Hz Or 60 beats per minute. The resting heart rate is 60 to 80 beats per minute. Learn how to make the sound effects of a heartbeat: www.libertivi.com/lelabodubruiteur_100. UCS Category: BEEPMed. Duration: 00:09.
Several beeps of an active sonar. This is a low frequency sonar (long range but low definition). It is a triangular wave of 1030 Hz frequency easy to put in loop. In reality, a military submarine usually has passive sonar, more sonar info: en.wikipedia.org/wiki/Sonar. UCS Category: BOATSub. Duration: 00:31.
Several beeps of an active sonar. This is a low frequency sonar (long range but low definition). It is a sine wave of 1190 Hz frequency easy to put in loop. In reality, a military submarine usually has passive sonar, more sonar info: en.wikipedia.org/wiki/Sonar. UCS Category: BOATSub. Duration: 00:21.
Beeps an electrocardiogram during cardiac arrest. This sound was made on computer. It is a square wave of frequency 835 Hz. UCS Category: BEEPMed. Duration: 00:24.
Distress signal "SOS" in international Morse (sound) alphabet. the Morse is formed of "dit" and "dah" (of points and features). 1 "dah" equals 3 "dit". The spaces between the letters are equivalent to 1 "dah", except for the SOS, which must be sent as if it were a single letter, that is to say not using an inter-letter interval. Ends with a space between the words equivalent to 7 "dit". Realized on a computer with a sine wave of 440 Hz. For more information on Morse: en.wikipedia.org/wiki/Morse_code. UCS Category: COMTelm. Duration: 00:03.
"Le Cri du Lynx®" is the new noise emitted by receding trucks, construction machinery, combine harvesters or other vehicles : www.cridulynx.fr/. This sound is easy to loop. UCS Category: BEEPVeh. Duration: 00:10.
Beep of a truck goes back. This sound was made on computer. It is a sinusoidal wave of frequency 1130 Hz. Easy to loop. UCS Category: BEEPVeh. Duration: 00:19.
Alarme d'incendie que l'on retrouve généralement dans les collectivités (Lycées, collèges, centres, etc.). Same sound as #0268 and #2250, but easy to loop. UCS Category: ALRMElec. Duration: 00:01.
