A disturbance level is defined as logarithm of frequency on base 2, so that a wide range of disturbances can be conveniently displayed on a manageable scale,

The frequency of yellow light is 5.8 x 10^{14} Hz = 2^{49} Hz. Therefore, the disturbance level of yellow light is referred to as DL49.

**The Disturbance Level is calculated as, DL = log (frequency) / log 2**

The Disturbance spectrum displays the frequencies of electromagnetic radiation and the de Broglie frequencies of mass particles in one place in the form of disturbance levels. Here are some of these disturbance levels.

**Radio Waves (3 Hz – 3 GHz) ……………. DL 1.6 – 31**

**Microwaves (3 GHz – 300 GHz) ………… DL 31 – 38**

**Infrared (300 GHz – 300 THz) …………… DL 38 – 48.5**

**Visible (400 THz – 800 THz) …………….. DL 48.5 – 49.5**

**Ultraviolet (800 THz – 30 PHz) ………….. DL 49.5 – 54.7**

**X-Rays (30 PHz – 30 EHz) ……………….. DL 54.7 – 64.7**

**Gammy Rays (> 30 EHz) …………………. DL 64.7 and greater**

**Electron ……………………………………… DL 66.7**

**Proton ………………………………………… DL 77.6**

**Neutron ………………………………………. DL 77.6**

**Earth ………………………………………….. DL 235.6**

This graph plots the levels of any disturbance as a function of frequency. The disturbance levels are defined in terms of the doubling of frequency. The basic disturbance DL0 has a frequency of 1 (2^{0}). The subsequent disturbance levels (DL 1, DL 2, DL 3 … DL n.) have frequencies of 2^{1 }(2), 2^{2} (4), 2^{3} (8) … 2^{n}. It can be seen from this graph that negative disturbance levels may be postulated to exist with the halving of frequency. The frequency never reaches the zero of ground state. As long as some frequency is present, awareness is also present in some form.
