The methods described will produce a suitable basis for the exchange of information or for direct comparison of the electroacoustical characteristics of the device. These methods are chosen to be practical and reproducible and are based on selected fixed parameters. The results obtained express the performance under the condition of the test, but will not necessarily agree exactly with the performance of the device under practical conditions of use.
