1823New Monthly Mag. VIII. 20 We should not be surprised to see this uncertainty brought, in time, under mathematical controul, by the invention of a musical Phonometer, to indicate the precise strength of sound. 1880Libr. Univ. Knowl. (N.Y.) V. 268 [Mentioned..among the inventions of Edison]. 1885Pall Mall G. 6 June, The Ministry are the most perfect phonometer in the world. Their decisions faithfully record the comparative strength of the noise that can be made by either of two conflicting sections.
Hence phonometric |fəʊnəʊˈmɛtrɪk| a., pertaining to a phonometer, or to the measurement of sound; phonoˈmetrically adv., using the methods of phonometry.
1895E. B. Titchener tr. Külpe's Outl. Psychol. i. iii. 156 The phonometric determination of sound intensity in psychophysical experiments is..usually carried out upon a principle similar to that employed in photometry. 1938Amer. Speech XIII. 282 Taking the long vowels of German which, merely for the sake of illustration, we shall assume are a phonometrically unclassifiable residue. Ibid. 278 This typical example of phonometric technique has clearly a considerable bearing upon both phonology and dynamic philology. 1965Jrnl. Appl. Physiol. XX. 302/2 Pressure determinations were made at the same time as the phonometric ones. |
