Online Tone Generator & Frequency Synthesizer
Generate exact audio frequencies from 20Hz to 20,000Hz with real-time waveform visualization. Test audio equipment, tune instruments, or eject water.
Online Tone & Frequency Generator
Generate pure sine, square, sawtooth, or triangle audio tones. Calibrate speaker drivers, test hearing range, and eject moisture.
๐ Acoustic Frequency Spectrum Guide
Understanding where different sound frequencies sit across the audible spectrum helps you diagnose speaker rattle, test subwoofer responses, or clear trapped moisture.
| Band | Range | Common Use / Application |
|---|---|---|
| Sub-Bass | 20Hz โ 60Hz | Subwoofer tests, 60Hz dust shaker tone, earthquake rumbles. Felt more than heard. |
| Mid-Bass / Water Eject | 60Hz โ 250Hz | 165Hz Sonic Water Ejection, bass guitars, kick drums. Maximum physical cone stroke. |
| Midrange / Vocal | 250Hz โ 2,000Hz | 440Hz Concert Pitch, 850Hz AirPods cleaning tone, human speech, telephones. |
| Presence / Treble | 2,000Hz โ 6,000Hz | Human ear maximum sensitivity zone. High vocal clarity, sibilance, violin overtones. |
| Brilliance / Ultrasonic | 6,000Hz โ 20,000Hz | Cymbals, air, hearing age tests (15kHz+), mosquito repelling sound experiments. |
๐ต Harmonic Solfeggio & Natural Tuning
Beyond hardware testing, our tone generator is used for acoustic sound meditation. 432Hz (Verdiโs A) is mathematically consistent with natural universe harmonics, while 528Hz is known as the "Miracle Tone" of Solfeggio frequencies for mental clarity and relaxation.

Frequently Asked Questions
Everything you need to know about acoustic water ejection and phone speaker maintenance.
How does this water eject sound actually work? +
When water enters a smartphone speaker grille, surface tension can trap liquid droplets across the fine mesh openings. Our tool plays a calibrated 165Hz tone with modulated pressure waves. This produces rapid vibrations designed to create localized air displacement and assist in forcing trapped moisture outward.
Does the water eject sound actually work? +
Yes, for liquid trapped on the outer speaker mesh and grille openings. The 165Hz tone causes the speaker cone to oscillate with rapid physical stroke excursion, generating air pressure pulses that help dislodge standing droplets. However, results vary based on liquid type (freshwater vs salt/soda) and exposure depth. It cannot fix internal electrical component damage if water breached deep motherboard circuits.
Will this sound damage my phone or earbuds speaker? +
No. The oscillator generates standard audio waveforms within safe consumer electronics frequency limits (20Hzโ20,000Hz), operating at normal playback output levels.
How many times should I run the cleaning cycle? +
We recommend running the 60-second cleaning cycle 2 to 3 times while keeping the speaker grille pointed downward toward a clean cloth. After each cycle, gently wipe the speaker ports, then test your audio clarity.
Can I use this on AirPods, Galaxy Buds, and Apple Watch? +
Yes. For AirPods and wireless earbuds, switch to the '๐ง Earbuds (850Hz)' mode, which is tuned for smaller micro-drivers. For Apple Watch or smartwatches, use the standard 165Hz mode.
Can I use uncooked rice to dry my phone speaker? +
No! Major phone manufacturers strongly advise against rice. Rice does not accelerate evaporation, and dry starch dust enters speaker ports and charging connectors, forming a cement-like crust that permanently mutes audio.
What if my speaker still sounds muffled after several cycles? +
If audio remains muffled, residual moisture may require more time to evaporate naturally, or dried mineral deposits may be obstructing the mesh. Prop your device upright in a well-ventilated room with cool airflow for 2โ4 hours. If distortion persists, contact an authorized repair provider.
Does this replace professional water damage repair? +
No. Acoustic ejection is an emergency first-aid step to assist in dislodging surface moisture from speaker openings. It cannot repair internal motherboard corrosion or replace damaged internal components. Results vary depending on device condition and liquid exposure.
