Sensory Overload in the Workplace: When Noise Becomes an Employee Barrier

Originally Published on LinkedIn

Something from my corporate career I didn’t understand until months later happened during a routine monthly client sync. I was running one of my favorite types of calls: reporting on monthly marketing performance. These calls are my CATNIP, for obvious reasons: present and translate monthly data into marketing insights based on structured thinking. I’m a marketing data nerd (we listen and we don’t judge), so data review calls are my game day. Usually, I can run these calls on rote, but that day, something really strange happened.

I started stumbling over words, lost my train of thought, and was struggling to present material I’d been working on for a week. At the time I chalked it up to nerves, a bad breakup, or maybe the move I was struggling through. Anything but the fuckshit that was actually making my brain bluescreen: A lawnblower. Outside. My window. Yes, neurodivergence can be this ridiculous on the outside: my nemeses are lawn blower and chainsaw sounds 😑

The bright side is that it reframed how I understand performance, environment, and neurodivergence in the workplace. So here’s a fun fact that took me wayyyyy too long to learn: sometimes what looks like anxiety is actually an acoustical issue.

The Modern Workplace Is Loud by Design

Think about your typical office building setup. You can add silence pods, a ping-pong table, and pizza Fridays, but that ignores the actual structure of the issue. Contemporary environments are saturated with mechanical noise:

• HVAC systems

• Printers and office equipment

• Open-plan chatter

• Construction

• Landscaping

Many of these sounds fall into low-frequency or irregular acoustic ranges, which happen to be the exact patterns human nervous systems evolved to interpret as environmental threat. For neurodivergent individuals (especially those with trauma-adapted nervous systems–so… let’s be real here… most of us) unpredictability matters as much as volume. An irregular sound pattern can prevent the brain from settling into a state of cognitive safety. When that happens, the nervous system shifts into heightened alert, and cognition pays the price.

When Sound Becomes a Threat to the Neurodivergent Employee’s Nervous System

Emerging research in acoustic neuroscience and trauma physiology suggests that certain sound frequencies can trigger sympathetic arousal before conscious processing occurs. How that plays out is that the body reacts before the mind understands.

That’s part of why some people experience:

• Sudden cognitive shutdown in noisy environments

• Need to stim, wear headphones, or leave meetings

• Speech disruption under unpredictable sound

• Rapid exhaustion in open-plan offices

It also explains why many neurodivergent professionals (myself included) report thriving during remote work. When we’re at home, we have control over the sensory inputs. Environmental predictability is a cognitive resource, and many workplaces unintentionally remove it.

Why This Disproportionately Impacts Neurodivergent Employees

Noise affects everyone, but not equally. Studies consistently show that noisy environments reduce productivity and increase stress across neurotypes. However, neurodivergent employees often experience amplified impact due to:

• Heightened sensory processing

• Lower tolerance for unpredictability

• Increased baseline cognitive load from masking

This creates a compounding effect: when we’re faced with more sensory input, we have less cognitive bandwidth, and less cognitive bandwidth means higher fatigue. The cherry on top is that all of these experiences are invisible, and if your entire team doesn’t also feel like there’s an electric shock rattling through their neurons every time they can’t predict the loud sound, then misinterpretations are inevitable. In reality, what appears to be disengagement may actually be sensory overload. What looks like anxiety may be sensory threat detection.

The Open-Plan Office/Employee Barrier Paradox

Many modern workplaces optimize for collaboration but create an employee barrier with sensory environment. Common challenges include:

• Constant overlapping conversations

• Equipment hum and vibration

• Lack of quiet retreat spaces

• Minimal acoustic buffering

Some organizations are beginning to address this through acoustic panels and partitions, focus pods or quiet rooms, hybrid work flexibility, and noise-aware workplace design. However, this doesn’t happen across the board in every office, and often considered an “employment perk” rather than a “reasonable accommodation.”

The Cost of Misunderstanding the Environment Erases How Neurodivergents Are Wired

When sensory challenges aren’t recognized, individuals internalize system failures. Neurodivergent employees are often forced to assume that we’re less resilient, professional, and capable. I’ve read stories from incredibly competent professionals who question themselves over environmental barriers they didn’t have language for. Heck, I’ve been one of them. 

Without shared understanding, we default to self-blame. And self-blame is expensive for people and organizations alike.

Shifting From Individual Fixes to System Awareness & Inclusion

Historically, the burden of adaptation has fallen on individuals. For real, ask us anything about:

• Noise-cancelling headphones

• Masking discomfort strategies

• Fidgets that don’t distract coworkers

• Working longer hours to compensate

Inclusion evolves when systems adapt too. That might look like designing quieter collaboration zones, providing predictable scheduling for disruptive maintenance, normalizing sensory conversations in workplace accessibility efforts, and training leaders on environmental barriers, not just interpersonal ones. Efforts like this make reasonable accommodations sustainable.

Rethinking Accessibility for Neurodiverse Companies

When we talk about workplace accessibility, we often think about mobility or visual accommodations. Those are great, don’t get me wrong, but accessibility also includes:

• Cognitive environments

• Sensory predictability

• Nervous system safety

Sound is part of infrastructure, and infrastructure shapes performance.

A Different Question

As conversations around neuroinclusion mature, the most important shift may be this:

Instead of asking: “Why is this employee struggling here?”

Instead: “What does this environment require nervous systems to tolerate?”

Because sometimes the barrier is actually acoustics. The more you know 🌈
