白噪声：White noise

White Noise acquired by sampling high-quality analog noise generator (Wandel & Goltermann). Exhibits equal energy per Hz. bandwidth. 

 

车内噪声：volvo

Volvo 340 noise acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). This recording was made at 120 km/h, in 4th gear, on an asphalt road, in rainy conditions. 

 

军用车辆噪音：Military vehicle noise

Leopard 2 noise acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). The Leopard 1 vehicle was moving at a speed of 70 km/h. The sound level during the recording process was 114 dBA. 

 

坦克内部噪声:Tank noise

M109 noise acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). The M109 tank was moving at a speed of 30 km/h. The sound level during the recording process was 100 dBA.

 

餐厅内嘈杂噪声：speech babble

Voice Babble acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). The source of this babble is 100 people speaking in a canteen. The room radius is over two meters; therefore, individual voices are slightly audible. The sound level during the recording process was 88 dBA. 

 

高频信道噪声：HF channel noise

Recording of noise in an HF radio channel after demodulation 

 

粉红噪声：pink noise

Pink Noise acquired by sampling high-quality analog noise generator (Wandel & Goltermann). Exhibits equal energy per 1/3 octave. 

 

机枪噪声：Machine gun noise

Machine Gun noise acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). The weapon used was a .50 calibre gun fired repeatedly. 

 

工厂车间噪音1：Factory floor noise 1

Factory noise acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). This noise was recorded near plate-cutting and electrical welding equipment. （板切割及电器设备焊接）

 

工厂车间噪音2：Factory floor noise 2

Factory noise acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). This noise was recorded in a car production hall. （汽车生产车间）

 

F16座舱噪声：F-16 cockpit noise

F-16 noise acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). The noise was recorded at the co-pilot's seat in a two-seat F-16, traveling at a speed of 500 knots, and an altitude of 300-600 feet. The sound level during the recording process was 103 dBA.It was found that the flight condition had only a minor effect on the noise. The reproduced noise can therefore be considered to be representative. 

 

驱逐舰机舱噪声：Destroyer engine room noise

Destroyer: Engine Room noise acquired by recording samples from microphone onto digital audio tape (DAT). The sound level during the recording process was 101 dBA. 

 

驱逐舰作战室背景噪音：Destroyer operations room background noise

Destroyer: Operations Room noise acquired by recording samples from microphone onto digital audio tape (DAT). The sound level during the recording process was 70 dBA. 

 

Buccaneer驾驶舱噪声1： cockpit noise；Buccaneer jet traveling at 190 knots;

Buccaneer noise acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). The Buccaneer jet was moving at a speed of 190 knots, and an altitude of 1000 feet, with airbrakes out. The sound level during the recording process was 109 dBA. 

 

Buccaneer驾驶舱噪声2： cockpit noise；Buccaneer jet traveling at 450 knots;

Buccaneer noise acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). The Buccaneer was moving at a speed of 450 knots, and an altitude of 300 feet. The sound level during the recording process was 116 dBA.
