How does noise affect amplitude and latency measurement of event-related potentials (ERPs)? A methodological critique and simulation study. Psychophysiology 2013 Feb;50(2):174-186. [doi: 10.1111/psyp.12001] [Me
How does wavelength affect sound?Sound:The sound is that form of energy which causes a sensation of hearing. Sound energy travels in form of waves which causes the pressure to change in the medium. A sound wave is characterised by its wavelength, frequency and amplitude....
A frequency response is a visual representation of how well an audio component reproduces the audible range of sound. It’s usually presented as a line graph, with the device’s output amplitude on the y-axis (in decibels) plotted against frequency on the x-axis (in Hertz). A fixed ampl...
Generally, the pulse widths are linked to the amplitude of the audio signal, and the spectrum of the pulses includes the desired audio signal plus undesired (but unavoidable) high-frequency content. The total integrated high-frequency power in all schemes is roughly the same, since the total ...
How does temperature affect frequency?Black-Body Radiation:Black-body radiation is the radiation which is produced by a perfectly opaque object that is in thermodynamic equilibrium with its surroundings. The temperature of a black-body does not change as it emits radiation....
Understanding frequency and amplitude in soundThe frequency and amplitude of sound waves as registered on an oscilloscope. See all videos for this article Sound waves have properties such as frequency and wavelength that affect how we perceive them.Frequency, measured inhertz, determines the pitch of...
and a further group of eight was tested at 86 dB SPL.Interestingly, the results demonstrated that the average amplitude level of the music playback did not affect the noise detection results. At each test level, the ability of listeners to detect the noise distortion depended on the relative ...
Ordinary sound waves are limited by their linear nature. Increasing the amplitude of the wave causes the sound to be louder, but it doesn't affect the shape of the waveform or cause it to be much more physically powerful. However, extremely intense sounds — like sounds that are physically ...
But you also have to consider the time axis, because if changes in amplitude fall between samples, they cannot be measured. Systems with greater than 100 dB dynamic range and at least 200 kS/s sample rate can handle most applications. For shock, noise, and vibration applications, a ...
