White noise … pink noise … red noise … brown noise … it is straightforward to get lost in the jungle of sound therapies if we do not take care, upstream, to clear all these notions. These types of treatments, which have been around for 30 years, may seem attractive when trying to reduce the presence and perception of tinnitus symptoms. Although their supposed effectiveness now gives them a real alternative status to be taken seriously, the fact remains that large-scale scientific studies are lacking in this area. However, because of the relative notoriety that they have acquired during the last three decades, it seemed appropriate to make an inventory on the subject. It will be interesting to discover how a white noise generator works and how this type of equipment intends to mask tinnitus. Also, how this form of therapy can speed up the process of habituation, a phenomenon that is known to play a significant role in the treatment of tinnitus symptoms.
What is a white noise generator?
It is a device that can be in different forms, more or less miniaturized. Conventional white noise generators are similar to portable radios that can be moved around easily so they can be used anywhere in the house.
Objective: To achieve the masking of tinnitus
The process of habituation in the line of sight
A habituation therapy to diminish the aversive connotation of tinnitus
The supposed virtues of white noise
Soothing and relaxing virtues
Less stress = less aversive connotation = less perception of tinnitus symptoms
The occupation of the sound space
Hyperstimulation of the nervous system
Concretely, this means that the disinterest will extend to tinnitus stimuli. Drowned in the field of white noise, tinnitus will be gradually banalized, they will lose some of their aversive connotations, which will have the effect of reducing their salience, i.e., their ability to arise in the foreground of our conscience.
