Hearing sensitivity

Noise that is background for others is unbearable for many neurodivergent people. It's not an exaggeration. It's not a whim. It's neurology.

Auditory hypersensitivity is one of the most common and least understood manifestations of neurodivergence. In this article, I explain what it is, why it occurs, and what you can do to manage it.

What is auditory hypersensitivity?

Auditory hypersensitivity—also called hyperacusis or atypical auditory processing—is an exaggerated response of the nervous system to sounds. The neurodivergent brain processes sensory stimuli with a different intensity, and sound is no exception.

For a neurotypical person, the sound of a crowded coffee shop might be background noise. For someone with ADHD or autism, that same sound can be physically painful, exhausting, or trigger a real stress response.

Why does it affect neurodivergent people more?

A neurodivergent person's nervous system often has different sensory thresholds. This means that the signal 'this sound is too much' is activated earlier, with more intensity, or takes longer to turn off.

In autism, sensory hypersensitivity is recognized as a diagnostic criterion. In ADHD, the difficulty in filtering irrelevant stimuli means that all sounds in the environment compete for attention at the same level.

Signs you have auditory hypersensitivity

• You get tired more easily than others in noisy environments.
• You need silence to concentrate where others can work with noise.
• Certain sounds cause immediate anxiety or irritability.
• Unexpected noise startles you excessively.
• You avoid crowded places due to the noise level.
• You always carry earplugs or headphones as a 'shield'.

Products that make a difference

Noise-canceling headphones

Noise-canceling headphones—originally designed for industrial environments—have become a sensory regulation tool for neurodivergent people. They reduce the decibel level of the environment without completely blocking it, allowing for calmer functioning.

At Neuromart, we offer noise-canceling headphones for both adults (−33 dB) and children (−24 dB).

Earplugs

For more discreet situations, earplugs are a convenient alternative. They are especially useful on public transport, in open-plan offices, or at social events.

Additional strategies for managing auditory hypersensitivity

• Identify your most sensitive hours (often at the end of the day).
• Create safe spaces at home with controlled noise levels.
• Communicate your needs at work or school.
• Use music or white noise as a 'shield' in noisy environments.
• Plan noisy events with prior and subsequent rest.

Auditory sensitivity is not a defect—it's information from your nervous system. And there are tools to manage it. Discover them at neuromart.shop.
