The first EVP recordings may have originated from the use of tape recording equipment with poorly aligned erasure and recording heads, resulting in the incomplete erasure of previous audio recordings on the tape. This could allow a small percentage of previous content to be superimposed or mixed into a new 'silent' recording. [57] [citation needed]
In contrast, humans are less averse to the white noise than to scraping. [4] A 1986 study used a tape-recording of a three-pronged garden tool similar to a fork being "grided" across a chalkboard, which roughly reproduces the sound of fingernails on chalkboard. The recording was then manipulated, removing pitches at the extremities and the median.
[58] [8] Double-layer CrO 2 cassettes have the lowest absolute noise among all the audio formulations; these cassettes generate less noise at 4.76 cm/s than a ferric tape at 19.05 cm/s. [53] Their sensitivity is usually also very high, but MOL is low, on par with basic Type I tapes.
The meaning of tonal in this context is in the sense of the amount of peaks or resonant structure in a power spectrum, as opposed to the flat spectrum of white noise.A high spectral flatness (approaching 1.0 for white noise) indicates that the spectrum has a similar amount of power in all spectral bands — this would sound similar to white noise, and the graph of the spectrum would appear ...

The white noise that is introduced by the radio is then also de-emphasized at the higher frequencies (where it is most noticeable) along with the pre-emphasized program, making the noise less audible. Tape recorders used the same approach to reduce "tape hiss" while maintaining fidelity.
