A noise floor is the level of an electronic circuit’s inherent noise. Hiss noise can be caused by electronic components, also known as self or inherent noise. This would sound similar to blue noise from a technical perspective. Hiss refers to a broadband noise covering the entire spectrum of the audible spectrum but is more intense in the higher frequencies.
