Some people do not understand the purpose for using sound enrichment at night. Neither do they know the correct way to administer it, or the importance of using good quality sound enrichment. It should not be regraded as a noise, on the contrary, it is a treatment for tinnitus and hyperacusis if it is present.
The brain and auditory system are always active, until the day we shuffle off this mortal coil. Someone with tinnitus risks making it louder and more intrusive if they sleep in a quiet room without using sound enrichment, because the brain has the ability to increase its background activity and in the process, increase the tinnitus which can make it louder during waking hours.
Placing a sound machine by the bedside or connected to a pillow speaker, will provide the brain and auditory system with sound enrichment and therefore, prevent it from increasing its background activity and the tinnitus. At the same time, if hyperacusis (oversensitivity to sound) is present, it will be treated, as the sounds help to desensitize the auditory system over time, so it becomes less sensitive to sound.
It is advisable to use nature sounds or something similar that is neutral and won't draw attention to itself or evoke emotions like music. Keep the sounds slightly below the tinnitus at all times and not masking it. It should be played throughout the night until morning.
The quality of sound enrichment is important and how it is administered. I don't advise using a mobile phone because the speaker is usually small and doesn't have much definition to the sound. If it's plugged into a docking station with external speakers or Bluetooth to a speaker then this should suffice.
