Why Noise Matters
Electric toothbrushes range from around 45 dB (barely audible) to 75 dB (similar to a hair dryer). Noise matters for early-morning brushing in shared homes, for children who are noise-sensitive, and for anyone who finds high-frequency vibration sound unpleasant. We measured or verified manufacturer noise ratings for the most popular models in 2026.
Noise Levels by Model (dB)
| Model | Noise (dB) | Price |
|---|---|---|
| Sonicare 9900 Prestige Next-Gen | 55 dB | $379.99 |
| SURI 2.0 | 58 dB | $134.99 |
| Quip Electric | ~45 dB | $25–$45 |
| Sonicare 4100 | ~65 dB | $49 |
| Oral-B iO Series 4 | ~60 dB | ~$99.99 |
| Oral-B Pro 3000 | ~70 dB | ~$59.99 |
| Oclean X Ultra | ~45 dB | $189.99 |
For reference: 60 dB = normal conversation; 70 dB = vacuum cleaner; 45 dB = quiet library.
Quietest Overall: Oclean X Ultra (~45 dB) and Quip (~45 dB)
Oclean's flagship and Quip both measure around 45 dB — effectively library-quiet. The Oclean X Ultra achieves this while still delivering 42,000 vibrations per minute, making it the best combination of quiet operation and cleaning power. Quip runs at lower vibration speeds which accounts for its low noise floor, but also means slightly less cleaning action than higher-speed models.
Best Value Quiet Pick: SURI 2.0 (58 dB)
At 58 dB the SURI 2.0 is quieter than a typical conversation and nearly 10 dB quieter than the Sonicare 4100. For $134.99 you get quiet operation plus a UV-C travel case, 38-day battery, and B Corp credentials. If quiet is your priority and you do not want to spend $190+, this is the pick.
Premium Quiet Pick: Sonicare 9900 Prestige Next-Gen (55 dB)
The 9900 Prestige Next-Gen is the quietest Sonicare ever at 55 dB — a significant improvement over the previous generation. If you want flagship Sonicare features with the lowest noise level in the lineup, this is it. The $379.99 price is the trade-off.

Frequently Asked Questions
What is the quietest electric toothbrush?
The Quip and Oclean X Ultra both measure around 45 dB. For sonic speed combined with quiet, the Oclean X Ultra is the quietest high-performance option. The Sonicare 9900 Prestige Next-Gen (55 dB) is the quietest flagship from a major brand.
Why are sonic toothbrushes loud?
Sonic brushes vibrate at 31,000–42,000 strokes per minute. The motor and brush head transmit some of that vibration as sound through the handle and into the jaw, amplifying perceived noise. Higher-end motors are better engineered to dampen this transmission.
Does a quieter toothbrush clean less well?
Not necessarily. The Oclean X Ultra is both quieter and faster (42,000 vpm) than many noisier models. Noise is a function of motor engineering and handle materials, not cleaning power.
