Results

Metric	Result
Capture RMS	2.094 mg
Capture peak	8.438 mg
Analysis range	1–40 Hz
1–8 Hz	15.69% energy · 0.830 mg RMS
8–20 Hz	12.89% energy · 0.752 mg RMS
20–40 Hz	71.42% energy · 1.770 mg RMS

Dominant local peaks

27.34 Hz · 0.982 mg; 17.61 Hz · 0.258 mg; 5.35 Hz · 0.249 mg; 28.32 Hz · 0.222 mg; 26.18 Hz · 0.218 mg.

Resonance context

Calculated cartridge/tonearm resonance: 7.87 Hz. The dominant local peaks are outside the comparison region, including 27.34 Hz, 17.61 Hz and 5.35 Hz. Measurement confidence was insufficient to classify a significant nearby feature, and most measured vibration energy lies above the predicted comparison region.

Scientific limitation: the phone measures mechanical vibration at its placement point. This contextual comparison does not directly measure or prove stylus/cantilever or cartridge/tonearm resonance, acoustic feedback, motor/bearing resonance, structural resonance, a specific cause or causation.
