Sone220 Top -

• Design: This piece features a contemporary, minimalist aesthetic. It is a long-sleeve top constructed from a semi-sheer, fine-gauge knit fabric, embodying a sleek, "second-skin" silhouette.
• Details: It typically includes a high mock neck and a form-fitting cut that emphasizes clean lines. The lightweight material allows for layering versatility.
• Styling: Designed as a staple layering essential, it pairs effectively under slip dresses, oversized knits, or tailored jackets to add texture and depth without adding bulk.

Abstract: Sone220 Top is presented as a compact, high-sensitivity acoustic sensor optimized for near-field sound measurement and voice-activated devices. This paper describes the sensor’s transduction mechanism, microfabrication process, characterization methods, and measured performance. Results show a flat sensitivity response from 100 Hz to 8 kHz with a calibrated sensitivity of −32 dBV/Pa, total harmonic distortion below 0.5% at 94 dB SPL, and a signal-to-noise ratio (A-weighted) of 72 dB, demonstrating suitability for consumer voice-capture and acoustic monitoring applications.

• Match power rating (higher is OK if same package size).
• Match resistance exactly (220Ω).
• Use isolated TO-220 if tab must be insulated from heatsink.
• Ensure heatsink surface flatness within 0.05mm.

Duct Size:

Most 220 CFM fans require a 6-inch duct. Using a 4-inch duct will "choke" the fan, increasing noise (raising the Sone level) and drastically reducing efficiency. Match power rating (higher is OK if same package size)
