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
