Protect Your Hearing.
Preserve Your Connection.
The first smart earbud designed specifically for dental professionals. Block damaging high-frequency noise from drills and scalers — while hearing your patients perfectly.
Ultrasonic scalers can reach 107 dB SPL — well above NIOSH's 85 dB safe limit.
82% of clinical studies found a positive association between dental work and hearing loss.
Nearly 1 in 3 practicing dentists report tinnitus, exceeding national averages in every age group.
96% of dentists do not use hearing protection — often because traditional earplugs block patient communication.

The Silent Epidemic in Dentistry
As a dental professional, you protect your eyes from aerosols, your back from poor posture, and your lungs from particulate matter. But every day, your hearing is left exposed to the relentless, cumulative damage of high-speed handpieces and ultrasonic scalers.
The problem is not just the volume — it is the frequency. Dental equipment operates in the 3–6 kHz range, precisely where human hearing is most sensitive and most vulnerable. This is the same range where speech intelligibility lives.
Sensorineural hearing loss is irreversible. Once the delicate hair cells in your cochlea are damaged, they do not regenerate. And traditional foam earplugs — while protective — eliminate the very communication that makes patient care possible.
"In every age group surveyed, tinnitus prevalence among dentists exceeded national averages."

Engineered for the Modern Operatory
Blocks the Drill, Not the Patient
Attenuates targeted tones commonly found in dental settings
Sonoshield's acoustic filters specifically target the damaging high frequencies (3–6 kHz) produced by high-speed handpieces and suction, while allowing human speech frequencies to pass through clearly.
Never Miss a Whisper
Maintains external speech clarity and environmental awareness
Maintain perfect situational awareness. Communicate effortlessly with your dental assistant and reassure your patients without ever needing to remove your hearing protection.
All-Day Clinical Comfort
Non-occlusive, selective filtering
Designed to be worn under loupes and face shields. The low-profile, lightweight earbud form factor ensures you can wear them for an entire 8-hour shift without fatigue.
"I need to protect my career, but I can't sacrifice my connection with patients."
The challenge every dentist faces. Sonoshield solves both.
Protecting the Vulnerable Left Ear
Research reveals a striking asymmetry: the left ear of dentists is disproportionately affected by hearing loss, a finding confirmed in 71% of studies reviewed in the landmark 2023 Griffith University systematic review. The reason is anatomical — the left ear is positioned closest to the patient's mouth and the noise-generating equipment.
The cochlear hair cells responsible for detecting high-frequency sounds (3–6 kHz) are the first casualties of noise-induced hearing loss. These cells are not just responsible for detecting the whine of a drill — they are the same cells that allow you to understand speech in a noisy environment.
Sonoshield's frequency-selective filtering technology acts as an acoustic barrier, compressing dangerous sound spikes before they reach the inner ear, while preserving the speech frequencies that make clinical communication possible.
Designed to reduce exposure to specific frequencies
Key Finding
Years of clinical experience is the most prominent risk factor for hearing loss in dental professionals — found in 82% of studies.

Protect Your Entire Team
Hearing loss doesn't only affect the dentist. Dental hygienists operating ultrasonic scalers and dental assistants managing high-volume evacuation (HVE) face equivalent occupational noise exposure throughout their careers.
Sonoshield is building solutions for individual practitioners and enterprise packages for Dental Service Organizations (DSOs). As occupational health standards evolve, proactive hearing conservation will become a competitive differentiator for forward-thinking practices.
