Temporal integration of loudness as a function of level

  • Poulsen, Torben (Project Manager)

    Project Details


    Temporal integration, ie the increase in loudness as a function of the duration of the signal, is investigated for brief tones and for noise bursts at different overall levels. Loudness matches between short and long signals (typically of durations of 5 and 200 ms) are obtained from levels close to the hearing threshold to levels well above the threshold. The aim of the investigation is to determine the loudness function for these sounds for both normal hearing and hearing-impaired persons.
    The project is carried out in collaboration with Mary Florentine and Søren Buus, Northeastern University, Boston, USA, and investigations on very steep hearing losses were carried out during their stay at DTU from August to December 1999.
