A world of solutions – ideal for Industrial, Engineering, Vehicle, Environmental & Building Acoustics applications – Noise Frequency
The Model 33 Noise Frequency Real-Time Analyser with 1/1 & 1/3 Octave Band Filters simultaneously measures all parameters with all Frequency and Time Weightings, giving you the confidence you will always have the correct data for analysis. This high-performance meter offers exceptional acoustic performance but it is still easy to use; taking measurements is as simple as pressing the ‘record’ and ‘stop’ buttons.
The Real Time Analyser allows you to measure all Octave Bands at the same time, immediately capturing all of the data in each band and not missing any important information. This is very practical for reliable, accurate and rapid capture of variable noise levels to optimise environmental monitoring surveys or provide an accurate prescription of hearing protection in industrial environments.
For environmental noise monitoring under BS 4142:2014, the large memory, programmable auto repeat function and statistical LN values, combined with the optional addition of an outdoor kit, ensures the instrument is ideal for use as either a short-term or longer-term semi-permanent environmental monitor. The ability to take measurements every 125ms allows the user to conduct detailed analysis for engineering and environmental noise. It is also available with remote management so you can see the real-time noise Frequency measurements at your computer whilst taking measurements elsewhere.
The wide dynamic span of over 110dB in the single measurement range ensures you never make invalid measurements that ‘Overload’ or ‘Under range’ which is especially important during 1:1 or 1:3 Octave Band Analysis. An extensions module is available to enhance both the low and high frequency limits of the 1:3 Octave Band Filters so that frequencies as low as 6.5Hz up to 20kHz can be measured.
The two outstanding powerful software packages, Analyser and Acoustic Toolbox software allow you to download, analyse in depth and present your results in a variety of formats.
