A European office equipment manufacturer needed to reduce noise levels from a high-volume microfiche camera. With Sontech acoustic solutions, a 4 dB(A) reduction was achieved — exceeding the target.
High-volume microfiche cameras generate substantial noise during operation, negatively impacting the work environment in offices and workrooms.
The customer required a minimum 3 dB(A) noise reduction. Additionally, all materials had to meet fire rating UL94HF1 — a strict standard for office equipment.
Measurements were performed with a Bruel&Kjaer type 2230 with octave/third-octave filters. Room dimensions 9×8 m, microphone positioned 1 m in front of the machine at 1.25 m height. Equivalent sound level Leq was recorded.
Sontech delivered a complete acoustic solution consisting of:
Tecnocell SA — Self-adhesive sound absorbent, fire-rated UL94HF1. Approximately 1 m² in various thicknesses applied inside the machine housing.
Dampfolie 25 SB — Self-adhesive vibration damping mat, fire-rated UL94V0. Applied to vibrating sheet metal surfaces to reduce structure-borne noise.
All materials were delivered as ready-to-install kits, custom-fitted to the machine geometry for fast and easy installation.
The final result showed a decrease from 64 dB(A) to 60 dB(A) — a 4 dB(A) reduction, exceeding the target of 3 dB(A).
Perceptually, 4 dB(A) represents a noticeable improvement in the sound environment. The reduction was achieved without affecting machine functionality or cooling.
Self-adhesive sound absorbent in various thicknesses, fire-rated UL94HF1. Approximately 1 m² total.
