DIN EN ISO 11688-2:2001 声学.低噪声机械和设备推荐设计惯例.第2部分:低噪声设计的物理学说明

The document describes the physical backgrounds of low-noise design rules for machinery and equipment given in DIN EN ISO 11688-1. It thus serves to detail the EU machinery safety directive (89/392/EEC). This standard explains the sound generation and propagation mechanisms in machinery, equipment and vehicles. It is distinguished between internal sources, transmission paths inside the machines and radiation from its boundaries. The document contains a glossary with definitions of thirteen terms.

ISO 12124:2001 声学.助听器真耳声特性的测量方法

This International Standard specifies procedures and requirements for measuring the real-ear acoustical characteristics of hearing aids. Its purpose is to ensure that the same measurements made on a given hearing aid on a given human ear and a given hearing aid, following the procedures described and using equipment complying with the requirements of IEC 61669, give substantially the same results. Measurements of real-ear acoustical characteristics of hearing aids which apply non-linear or analytical processing techniques are valid only for the test signals used and conditions employed. These measurements should be performed in accordance with the hearing aid manufacturer's recommendations as they may require specific test signals or test conditions outside the scope of this International Standard.
