Reclaim the Silence

Personalized bone conduction acoustic enrichment for tinnitus, informed by two decades of auditory neuroscience. We’re building a device that addresses the underlying neural mechanism—not just the symptom.

The Problem

Tinnitus isn’t a sound.
It’s your brain filling a void.

When acoustic trauma or aging damages hair cells in the cochlea, neurons in the central auditory system lose their normal input. The brain doesn’t stay quiet—it compensates. Spontaneous firing rates increase. Tonotopic maps reorganize. Neurons at the edge of hearing loss become over-represented. The result is a phantom percept: tinnitus.

You know the sound. It’s there when you wake up. It’s there when the room goes quiet. You’ve tried white noise apps, sound machines, maybe even medication. Nothing addresses why it started.

iSilentium was born from lived experience with acoustic trauma and the frustration of approaches that manage around the problem instead of engaging with it.

The Science

From deafferentation to rebalancing

Tinnitus is maintained by a cascade of maladaptive neural plasticity. A growing body of research suggests that the same plasticity can be leveraged to modulate the underlying neural activity.
1
Cochlear Deafferentation
Noise exposure or aging damages hair cells and synaptic connections in the cochlea. Central auditory neurons lose their afferent input, particularly at high frequencies (typically 4–8 kHz). Even hidden hearing loss—synaptic damage not reflected on a standard audiogram—can trigger tinnitus.
Eggermont & Roberts, 2004; Kujawa & Liberman, 2009
2
Maladaptive Cortical Reorganization
Without normal input, the auditory cortex reorganizes. GABAergic inhibition weakens. Neurons in the hearing loss region shift their tuning to edge frequencies, which become over-represented. Spontaneous firing rates and neural synchrony increase—the brain interprets this aberrant activity as sound.
Noreña & Eggermont, 2005; De Ridder et al., 2011
3
Spectrally-Shaped Enrichment
Research demonstrates that delivering acoustic energy calibrated to an individual’s hearing loss profile can re-stimulate deprived neuronal populations. This process may strengthen lateral inhibitory circuits and reduce the spontaneous hyperactivity associated with the tinnitus percept.
Pantev et al., 2012; Okamoto et al., 2018; Noreña, 2010
4
Bone Conduction Delivery
Unlike air-conducted sound, bone conduction bypasses the outer and middle ear entirely, transmitting vibrations through the skull directly to the cochlea. This preserves natural hearing while simultaneously delivering targeted frequencies. Early pilot studies of bone conduction sound therapy for tinnitus have reported encouraging results on validated tinnitus indices.
Holgers & Håkansson, 2002; Eça et al., 2025
Our Approach

Engaging the mechanism,
not just the perception.

Audiogram-Calibrated Enrichment
Your audiometric profile maps the frequencies where your cochlea has lost sensitivity. iSilentium generates spectrally-shaped tone pips weighted to your specific hearing loss pattern—a personalized acoustic environment, not generic broadband noise.
Bone Conduction Transduction
Dual mastoid-mounted bone conduction transducers deliver the enriched acoustic environment directly through the temporal bone to the cochlea. Your ear canals stay open. Your natural hearing stays untouched. The enrichment runs in the background of your daily life.
On-Device Processing
An ESP32-S3 microcontroller handles signal generation and calibration entirely on-device. No cloud dependency. No data collection. The spectral curve is tuned to your hearing profile and can be refined as your audiometric needs evolve.
Grounded in Published Research
Built on two decades of peer-reviewed work on auditory cortical reorganization, lateral inhibition, and tailor-made notched music training (TMNMT). We apply these established mechanisms through a purpose-built wearable rather than repurposed consumer hardware.

Common Questions

What you’d want to know

Is this another white noise machine?
No. White noise and sound masking aim to cover the tinnitus percept—they don’t address the underlying neural activity. iSilentium delivers spectrally-shaped acoustic enrichment calibrated to your individual hearing loss profile, informed by research suggesting this approach can modulate the cortical reorganization associated with tinnitus.
Why bone conduction instead of regular headphones?
Bone conduction bypasses the outer and middle ear entirely, transmitting vibrations through the skull directly to the cochlea. This means your ears stay open for normal hearing and conversation while the enrichment signal is delivered simultaneously. It also avoids occlusion-related discomfort common in tinnitus patients.
Is this FDA-cleared?
No. iSilentium is currently a research-stage concept under active development. It has not been submitted to or cleared by the FDA. It is not intended to diagnose, treat, cure, or prevent any disease. We are transparent about where we are in development and will update our community as milestones are reached.
Do I need an audiogram to use it?
The spectral enrichment curve is shaped by your hearing loss profile, so an audiogram is the foundation of personalization. We recommend getting a comprehensive audiometric evaluation from a licensed audiologist, which also serves as an important baseline for tracking any changes over time.
When will it be available?
We’re currently in Phase 1—validating bone conduction delivery of spectrally-shaped signals at loss frequencies. Phase 2 will transition to a consumer-ready wearable form factor with a companion app. Join the waitlist to follow our progress and be among the first notified.
