The SoundPro™ SE/DL series provides advanced sound level monitoring and comprehensive data analysis. Available in Class 1 and Class 2 models, these instruments feature large screen displays that enable real-time frequency analysis and data storing capabilities. Octave band analysis enables environmental noise monitoring, noise enforcement, and noise control evaluation.
Preamp can be easily removed to enable interference-free low-level monitoring, especially for environmental noise applications.
Large display with intuitive pushbutton/soft key interface offers easy viewing and navigation. Provides quick access to data.
Optional acoustic spectral curves, speech intelligibility and reverberation add-ons enable advanced monitoring and analysis functions.
