Individual loudness functions have been obtained by a form of magnitude estimation for 15 observers. The experiments took place over a period of five months and used two different procedures. The results show that most of the individual observers can produce a loudness function of consistent slope and that in many cases this slope is significantly ...

Perstimulatory loudness adaptation
The Journal of the Acoustical Society of America, 1973An experiment is described in which perstimulatory loudness adaptation was measured under heterophonic conditions using simultaneous dichotic loudness balance procedures on normal listeners. The adapting signals were 500 and 3000 Hz presented at 70 dB SPL for 12 min, the last 5 min of which involved perstimulatory loudness balances.

The American Journal of Psychology, 1973
The present study employed 600 subjects and extended earlier experiments under 'ideal' conditions to white noise. When known experimental biases were eliminated, half loudness was equal to half sound-pressure level (-6 dB) from 45 through 90 dB. The same simple relation held whether stimulation was through headphones or loudspeaker, and whether ...

An electrical loud speaker is a device applied to radiophone reproduction of speech and music. This paper brings out the mechanical and electrical essentials of this device and gives a short description of present-day forms and methods used in developing and testing new types.
