Playing selected types of music on five different personal cassette players (PCPs) and using different gain (volume) settings, A-weighted maximum and equivalent sound pressure levels (SPLs) were measured on KEMAR (Knowles Electronics Manikin for Acou

Playing various types of music on five selected personal cassette players (PCPs), A-weighted sound pressure levels (SPLs), together with octave band spectrum, were measured on KEMAR (Knowles Electronics Manikin for Acoustic Research). Maximum and equ

In most textbooks, it is stated that noise-induced hearing loss (NIHL) is an irreversible impairment of hearing. This is certainly true for the slowly, over time acquired NIHL. Working for years in a very noisy environment is causing a gradual killin

Inception of hearing and opening of eyelids were examined in cat, rabbit, dog and mink. The hearing tests were performed with pure tones and bands of noise observing various types of behavioural responses. Hearing was found to occur at an average age

The middle-ear muscle reflex threshold for bone-conducted pure tones (250–6 000 Hz) was compared with the corresponding threshold for air-conducted tones. In normal-hearing subjects a significant difference (5–25 dB) was found. Possible causes fo

The concept of the critical band, or Frequenzgruppe, is shown to apply to loudness summation. When the spacing between a group of pure tones is increased, the loudness remains constant until a critical point is reached, after which the loudness incre

In 186 ears of 115 patients, impedance changes at the onset and at the end of the stimulus (“diphasic impedance changes”) were recorded, using Madsen Impedance Instruments Model ZO 61 and Model ZO 70. The eliciting stimuli were:1. Tactile stimulu

Measurements of “music noise” spectra in various youth centres show great variations in levels in rooms with different acoustic properties. The noise spectra from different orchestras are, however, remarkably equal. The high level and the narrow

Behavioural responses have been elicited to acoustic stimuli in hereditarily deaf white mink (Hedlund). This revealed onset of auditory function at an average age of 31 days. The period of hearing lasted on the average only 7 days. Similar observatio
