High frequency sound causes two types of health effects: on the one hand objective health effects such ashearing loss(in case of protracted exposure) and on the other hand subjective effects which may already occur after a few minutes: headache, tinnitus, fatigue, dizziness and nausea. Do high...
Mere presentation of high-frequency sounds did not produce any effects4. In addition, the comfortable listening level to which the listener adjusted the sound intensity was higher for full-range sounds than for high-cut sounds5,6. These effects peaked when the intensity of high-frequency ...
Given the relatively young age group of test subjects, it was expected that a reasonable sensitivity to this higher frequency would be apparent; this was also confirmed by the test results (mean 18 dB HL @ 16 kHz, SD = 12, for both left and right ears). 2.2. Experimental tasks The ...
The effects of the bandwidth of high-frequency sounds on loudness are investigated. Loudness matches are obtained using a two-interval, adaptive forced-choice procedure converging on the point of subjective equality by following a simple 1-up, 1-down rule. Loudness increases significantly when the ...

What frequency is damaging to humans? Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. Most mobile operators use from radiofrequency waves in therange up 300 MHz to 3 GHzthat can be harmful for...

While the audible frequency range for humans spans approximately 20 Hz to 20 kHz, children display enhanced sensitivity relative to adults when detecting extended high frequencies (frequencies above 8 kHz; EHFs), as indicated by better pure tone thresholds. The impact that this increased hearing sen...
