The most sensitive human ears top out at 20 kHz, but there are someinteresting EQsthat allow you to boost at frequencies even higher. This part of the spectrum is well outside the audible range. But these boosts are so broad that their effects radiate down through the spectrum and cause a...
Sound characteristics in low frequency noise and their relevance for performance effectsNoise surces with dominating low frequencies (<200 Hz) are commonly found in working environments. In two previous studies, work efficiency and work quality was found to be impaired to a larger degree when ...
Spectral methods of sound synthesis involve observing a sound wave’s frequency spectrum (the frequencies and amounts of each of the components that make up the sound) and re-creating that spectrum to mimic the original. Most of the sounds we hear in the real world are broadbanded; that is...
We found that generalization could indeed be broad, such that sound clouds of frequencies that do not overlap with the conditioned sound also elicited changes in NREM EEG patterns. This was not related to the discriminability of the sound clouds, since mice trained to discriminate between these ...
waveforms contain harmonics, which are also sine waves but with frequencies that are integral multiples of the base frequency. The timbre demo changes the waveform smoothly from a sine wave to a triangle wave, to a square wave, to a sawtooth wave, while increasing the harmonic ...
The waveform carrier is a tool that can build a sound effect with a serie of specific frequencies passed as argument to the function (all frequencies will be mixed together). Each sub frequency singnal will have their amplitude decreased compare to first frequency (carrier signal). ...
Key influencing factors were analyzed, and the regulation law of new piezoelectric resonance frequencies was clarified. Keywords: acoustic metamaterial; shunted piezoelectric patches; honeycomb core sandwich plates; sound transmission loss; effective medium method 1. Introduction The honeycomb core sandwich ...
I had been searching for a while to find someone who could teach about sound therapy from a deeper understanding of sound frequencies and how they affect the body. How to work with this in sessions. I loved the different components of teaching, acquiring knowledge, practising and having to do...
Understanding frequency and amplitude in soundThe frequency and amplitude of sound waves as registered on an oscilloscope.(more) See all videos for this article This means that sound waves with high frequencies have short periods, while those with low frequencies have long periods. For example, a...
2) on eight mice in which we played (1) white noise of various intensities, (2) pure tones of various frequencies and (3) white noise coming from various locations. In contrast with the previous experiments, auditory stimuli were presented using an array of seven speakers (102-1299-ND, ...
