Results

Metric	Result
Capture RMS	1.266 mg
Capture peak	5.956 mg
Analysis range	1–40 Hz
1–8 Hz	38.67% energy · 0.787 mg RMS
8–20 Hz	25.84% energy · 0.644 mg RMS
20–40 Hz	35.49% energy · 0.754 mg RMS

Dominant local peaks

6.62 Hz · 0.229 mg; 5.35 Hz · 0.172 mg; 7.78 Hz · 0.140 mg; 17.42 Hz · 0.135 mg; 12.07 Hz · 0.134 mg.

Resonance context

Calculated cartridge/tonearm resonance: 7.87 Hz. A local spectral maximum occurs at 7.78 Hz near the predicted resonance region, but measurement confidence was insufficient to classify it as a significant/confident nearby feature.

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.
