NOISE-92噪声数据集，用于语音信号处理

美国国家标准局(ANSI)与国际标准化组织（ISO）已经制定了SQL标准。ANSI是一个美国工业和商业集团组织，负责开发美国的商务和通讯标准。ANSI同时也是ISO和International Electrotechnical Commission(IEC)的成员之一。ANSI 发布与国际标准组织相应的美国标准。1992年，ISO和IEC发布了SQL国际标准，称为SQL-92。ANSI随之发布的相应标准是ANSI SQL-92。ANSI SQL-92有时被称为ANSI SQL。尽管不同的关系数据库使用的SQL版本有一些差异，但大多数都遵循 ANSI SQL 标准。SQL Server使用ANSI SQL-92的扩展集，称为T-SQL，其遵循ANSI制定的 SQL-92标准。

很有用的噪声库，可进行语音信号处理的离线仿真测试等 File: Matlab or WAV formats (compressed) sampling rate: 19.98 KHz A/D: 16 bit pre-filter: anti-aliasing filter pre-emphasis: none filter: none duration: 235 sec length (uncompressed): approx 9 Mb (uncompressed) 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
