“…The pure tone absolute threshold data suggest that the frequencies of greatest TTS were 4 and 6 kHz, which is in agreement with many previous studies using exposure to broadband noise stimuli (Axelsson and Lindgren, 1978;Jerger and Jerger, 1970;Rupp and Koch, 1969;Ulrich and Pinheiro, 1974). The mean TTS was 10.8 dB, which is less than shown in previous studies for which TTS averaged 15e37 dB (Axelsson and Lindgren, 1978;Drake-Lee, 1992;Jerger and Jerger, 1970;Rupp and Koch, 1969;Tin and Lim, 2000;Ulrich and Pinheiro, 1974).…”
