The Massachusetts Hearing Test
Philip W. Johnston · The Journal of the Acoustical Society of America · 1948
A combination speech-pure tone group test technique is described in which standard phonograph speech audiometer equipment is readily converted for dual test use through the addition of a commercial discrete frequency audiometer and an inexpensive coupling unit. The group pure tone section of the test is rapidly scored. The group pure tone section of the test is shown to possess a marked superiority over the phonograph record test in terms of correlation with individual pure tone test criteria.
