Simple Process
Order & Shipping
Place an order and you will receive your device within 1-2 weeks. The provided email address receives an invitation to log in to your Sonotrazer account.
Data Collection
Place the system in a room to be monitored and switch it on. A high frequency-definition 12.5 Hz–20 kHz spectrum of the measured microphone signal is continuously recorded every ~10 seconds.
Return
Pre-paid post shipping label to return the original package. Your measurement data will be put online after reception of the package, so you can access it.
Advanced Analysis Tools
- User-defined Frequency Groups
- Unparalleled frequency resolution
- Event tagging
- Interactive Spectrogram & Spectrum plots
Identify Sources
Get an overview of the daily and weekly on/off cycles of the different noise sources in your neighbourhood. Long-lasting steady noise patterns and short-term impulsive noises are both revealed.
Privacy by Design
- Only averaged 10-second spectra are stored; no speech can be retrieved.
- All wireless connections on the measuring device are disabled.
- Measurement data is saved locally on a USB drive.
Results
A monitoring campaign provides answers to:
- Is there an audible noise in my environment?
- Can the noise level overshoot the legal limit?
- What type of source(s) can it be?
Next Steps
With new information at hand, more precise action can be taken to address the issue on the field.
