Stenger, in 1907, published an article on the detection of malingering, which had implications beyond the simple unmasking of feigned unilateral deafness.1 Stenger's test demonstrated clearly that when we are exposed to a sound presented simultaneously to the two ears, we experience not separate sensations at each ear, but rather a single sound which has a single location.

In recent years many papers have been published in which various interaural effects were explored experimentally.2-5 The primary clinical application of these effects, however, continues to be the Stenger test for malingering.

For some years we have been interested, at Hunter College, in the application, to clinical tests of hearing, of the fusion effects which occur when the two ears experience a common sound at different intensities.6-9 Among other applications it appeared to us that these effects could be better exploited in the determination of thresholds of hearing sensitivity
