Asd 4 year old hates noise but is so loud.

hi

my 4 year is on the ASD pathway and also has global develpoment delay which puts him at around 2 years old. he also suffers from sensory processing disorder.

he struggles with loud noises and has ear defenders for when he finds it tough however, i am struggling as he is so loud he shouts when he talks and is really loud when he plays aswell. how do i manage this as he doesnt understand quiet when i try to explain to him. also he struggles with spd so he bangs his body on things constantly rubs himself all day long. how do i explain to people that he struggles with noise but not his own noise. ( i am not even sure if that makes sense) he has no problems if he is banging or shouting just other peoples noise.

any help would be great in trying to explain this.

  • Hello, I have not found investigation related to autism on this but my son has something similar and lately he even puts his fingers in his ears before screaming. I suspect it comes from the control of the accoustic reflex. In our inner ear a muscle can block noise as a reflex, a bit like roosters who would become deaf from own "voice":

    • The acoustic reflex is also invoked when a person vocalizes.[15] In humans, the vocalization-induced stapedius reflex reduces sound intensities reaching the inner ear by approximately 20 decibels. The reflex is triggered in anticipation of the onset of vocalization.[15] While the vocalization-induced stapedius reflex in humans results in an approximate 20 dB reduction in transduction to the inner ear, birds have a stronger stapedius reflex that is invoked just before the bird tweets.[16]

    I can imagine that someone highly sensitive to noise need to help his own inner muscle in some way especially for unexpected loud noises.
