WARNING: This sound is dangerously powerful, and with great power. The results showed that Roughness, Loudness and an index defined as High frequency tonality were the most important characteristics. Learn how to make the most annoying sound in the world all you need is 2 empty drink cans. The third part was performed by children to validate the results. In the second part, teachers working with autistic children performed a listening test to evaluate some of the composed sounds from part 1 and modified versions of them. First 16 children composed different types of vacuum cleaner sounds trying to minimize annoyance in two different tests, a) keeping original sound pressure level. Detailed psychoacoustic analyses of this type of sounds were achieved by a listening test procedure in three parts. The results, published in the Journal of Neuroscience, show the top 10 most unpleasant sounds (and you can click on the first five to hear the sound): 1. Examples are vacuum cleaners, ventilation noise, washing machines and pouring water. By interviewing teachers and parents a number of everyday sounds were identified and binaurally recorded. The aim of this study is to increase the knowledge about these extremely annoying sounds so they can be avoided by better design criteria for classrooms and venues like that. On their own, repetitive mouth noises (such as humming, grunting, whistling, repeating sounds) are very rarely a cause for concern. However, the characteristics and temporal variations of these sounds are sparsely investigated. In the video below, a tone slowly rises from a superlow 20-hertz tone to a 1,000-times-higher 20 kilohertz. A sound that is extremely annoying does not need to be loud. That's a very high-pitched sound much higher than most adults can hear. Extreme sensitivity to noise is a problem that almost all autistic children suffer from.
