Abstract
From time to time attention has been given to the objective reality of so-called ‘combination tones’ produced when two simple tones are sounded together. We have recently had an opportunity of investigating this experimentally, using a wave analyser of the degenerative type, employing an electronic circuit described by one of us1. The analyser has a high selectivity corrresponding to a Q value of about 100.
