A procedure was developed for the automated measurement of the speech reception threshold in stationary noise (SRTn), which can be administered by the subjects themselves using a computer. The procedure was based on the SRTn test for Dutch developed by Plomp and Mimpen [(1979). “Improving the reliability of testing the speech reception threshold...

A rigorous application of the traditional definition of sonar equation terms leads to the appearance of an unexpected factor, not routinely included, equal to the ratio of the characteristic impedance at the receiver to that at the source. An omission of this factor can lead to non-negligible errors for realistic conditions. It is further argued...

An expression is derived for the computation of the time average of a function f(t). Based on this expression, a principle is discussed realizing continuous computation of the time average of the input signal. Some practical circuits are discussed. These circuits offer several advantages over classical solutions. An expression is derived for the...
