phonometern.

Brit.

/fə(ʊ)ˈnɒmᵻtə/, U.S.

/foʊˈnɑmədər/

Origin: Formed within English, by compounding. Etymons: phono- comb. form, -meter comb. form².

Etymology: < phono- comb. form + -meter comb. form². Compare French phonomètre (1818 or earlier), Italian fonometro (1829).

An instrument for measuring or automatically recording the intensity of sound.

1823 New Monthly Mag. 8 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.

1888 Appleton's Cycl. Amer. Biogr. II. at Edison, Thomas Alva The phonograph..and the phonometer and apparatus for measuring the force of sound-waves produced by the human voice, are inventions of this period.

1965 Jrnl. Appl. Physiol. 20 302/1 It was assumed that the changes of sound intensity, as given by the phonometer, were proportional to the changes of the intensity of the sound produced.

2005 Clin. Neurophysiol. 116 192/2 (note) The noise level..was measured with a phonometer (which integrates the sound energies of the environment over time).
