noisex92雜訊庫各種雜訊介紹    File: Matlab or WAV formats (compressed) sampling rate: 19.98 KHzA/D: 16 bitpre-filter: anti-aliasing filterpre-emphasis: nonefilter: noneduration: 235 seclength (uncompressed): approx 9 Mb (uncompressed)  白色雜訊：White noiseWhite Noise acquired by sampling high-quality analog noise generator (Wandel & Goltermann). Exhibits equal energy per Hz. bandwidth.  車內雜訊：volvoVolvo 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.  軍用車輛噪音：Military vehicle noiseLeopard 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.  坦克內部雜訊:Tank noiseM109 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. 餐廳內嘈雜雜訊：speech babbleVoice 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.  高頻通道雜訊：HF channel noiseRecording of noise in an HF radio channel after demodulation  粉紅雜訊：pink noisePink Noise acquired by sampling high-quality analog noise generator (Wandel & Goltermann). Exhibits equal energy per 1/3 octave.  機槍雜訊：Machine gun noiseMachine 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.  工廠車間噪音1：Factory floor noise 1Factory 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. （板切割及電器裝置焊接） 工廠車間噪音2：Factory floor noise 2Factory 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. （汽車生產車間） F16座艙雜訊：F-16 cockpit noiseF-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.  驅逐艦機艙雜訊：Destroyer engine room noiseDestroyer: Engine Room noise acquired by recording samples from microphone onto digital audio tape (DAT). The sound level during the recording process was 101 dBA.  驅逐艦作戰室背景雜音：Destroyer operations room background noiseDestroyer: 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駕駛艙雜訊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駕駛艙雜訊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.
