acoustic shock

Acoustic Shock Disorder (ASD) is the term for persistent symptoms following an acoustic shock: a reaction to a sudden, unexpected sound. This can include tinnitus, sound sensitivity, ear pain, a feeling of pressure in the ear, and anxiety regarding new sounds.

The sound itself may have long since passed, but the effects can linger. A conversation, a crowded room, or an unexpected noise can trigger tension or discomfort all over again. This can impact your sleep, concentration, work, and social life.

What is it?

What is an acoustic shock?

An acoustic shock can occur after a brief, unexpected sound, such as a sharp tone through headphones, a bang, or sudden noise nearby.

Symptoms can be temporary and subside. When they persist and affect daily functioning, the term Acoustic Shock Disorder is used.

‍

What symptoms can occur?

Symptoms vary from person to person and can occur together:

Tinnitus or ringing in the ears:hearing a ringing, buzzing, or humming sound without an external sound source.
Hyperacusis:perceiving ordinary sounds as excessively loud, unpleasant, or overwhelming.
Pain from sound — noxacusis:sounds cause pain, sometimes even at low volume levels.
Ear symptoms:pressure, a feeling of fullness, tension, or pain in and around the ear.
Other symptoms:dizziness, head, neck, or jaw pain, and anxiety regarding new sounds.

Persistent distress can also lead to sleep problems, difficulty concentrating, fatigue, or feelings of sadness. During the assessment, we therefore look at the entire pattern of symptoms.

‍

Can you have symptoms with a normal hearing test?

Yes. After an acoustic shock, a standard hearing test may show normal hearing thresholds, even though you are still experiencing tinnitus, ear pain, or sound sensitivity.

A hearing test measures how well you hear certain tones. The test does not map all aspects of sound processing, pain, and sound sensitivity. That is why we always evaluate the results in conjunction with your symptoms and an examination of the ear.

‍

How do these symptoms develop?

The mechanism behind Acoustic Shock Disorder is not yet fully understood.

Research describes a possible interaction between the middle ear, nerve pathways for pain and sensation, sound processing, and the startle and stress response.

One of the explanations being researched concerns thetensor tympani, a small muscle in the middle ear that influences the tension of the eardrum.
An excessive reaction of this muscle and the associated nerve pathways could contribute to pressure, tension, or pain around the ear.
This explanatory model is still being investigated.

‍

What role does stress play?

After an unexpected sound incident, you may become more alert to sound.
You might find yourself constantly listening for incoming sounds and trying to avoid situations that could trigger symptoms.

Tension, pain, and sound sensitivity can then reinforce one another.

That is why we focus on both the ear and sound-related symptoms as well as the impact on sleep, emotions, and daily functioning.

‍

How is ASD related to tinnitus and hyperacusis?

ASD describes the persistent pattern of symptoms following a sound incident.
Tinnitus and hyperacusis can be part of this, but they also occur without an acoustic shock.

With tinnitus, you hear a sound without an external source. With hyperacusis, you experience environmental sounds as too intense or distressing.
Following an acoustic shock, both symptoms can be accompanied by ear pain, tension, and a fear of sound.

How to treat

How do we treat Acoustic Shock Disorder?

We recommend consulting an ear, nose, and throat (ENT) specialist first. They will examine any potential hearing damage, middle ear problems, and other treatable causes.

‍In the event of sudden hearing loss following a sound incident, a prompt medical evaluation is necessary.

If symptoms persist, we will determine the appropriate treatment at BRAI3N.

We work in four phases.

‍

1. Assessment

We listen to your story and discuss the sound-related incident, your symptoms, and any previous examinations or treatments. We look at which sounds are distressing, whether you experience pain, and how your sleep, concentration, and daily life are affected.

A qEEG, a measurement of electrical brain activity, may be part of this assessment. We review the results alongside medical and clinical findings to develop a treatment plan.

Goal: to understand what is going on.

‍

2. Targeted treatment

We begin treatment according to the agreed-upon protocol. The approach may consist of a combination of:

Neuromodulation:using non-invasive techniques, we influence brain networks involved in tinnitus, sound processing, attention, and the reaction to sound. The goal is to reduce symptoms and the associated distress.
Psychotherapy:support for sound sensitivity, persistent tension, and the impact of your symptoms on your daily life. You will receive this guidance outside of BRAI3N, for example, with a local psychologist.
Medication:when a physician deems it appropriate, for example, for associated pain, depression, or sleep problems.

Neuromodulation is not a miracle cure. We therefore discuss expectations and carefully monitor how the treatment affects you.

‍

3. Stabilization

If the treatment is effective, we build on the results achieved. Sessions become gradually less frequent to assess whether the improvement is maintained.

We monitor both your symptoms and your daily functioning: are you tolerating sounds better, sleeping more soundly, and finding it easier to resume activities? The pace is tailored to your progress.

‍

4. Maintenance

We look for the lowest treatment frequency required to maintain the effect. Some people still need maintenance sessions, while others do not.

Together, we discuss whether further treatment is useful and when a new evaluation is appropriate.

‍

After each phase, we evaluate the results together and decide on the next step.
This ensures the process remains tailored to your symptoms, progress, and needs.

‍

Managing sound and hearing protection

Hearing protection remains important for harmfully loud sounds. However, wearing earplugs constantly in normal, safe sound environments can increase sound sensitivity.

We therefore discuss when protection is necessary and how you can gradually reintroduce everyday sounds within your tolerance levels. Any increase in sound exposure is done gradually and under guidance. Exposure that causes pain or clear worsening of symptoms is never forced.

‍

Are sounds still dictating your daily life?

A persistent ringing, pain from ordinary sounds, or the fear of a new loud noise can be incredibly draining.
During an intake session, we will map out your situation and discuss which approach best suits your symptoms.
