NTi Audio Introduces Outdoor Noise Monitoring Solution for XL2 Sound Level Meter

October 3 2014, 08:00
A tailored solution from NTi Audio for outdoor noise monitoring is now available for the XL2 Sound Level Meter. The new outdoor measurement microphone M2230-WP and the heavy-duty outdoor case ideally complement the XL2 system for unattended noise monitoring.

The XL2 Sound Level Meter simultaneously measures broadband levels, the detailed noise spectrum and records the audio signal. Combined with the new outdoor measurement microphone M2230-WP and outdoor case, creates the ideal solution for annoyance assessments and outdoor noise measurements.

The measurement microphone M2230-WP was designed by NTi for precise noise measurements outdoors. The corrosion-free polymer housing, wind screen, water-repellent membrane and bird spike provide excellent protection from rain, wind, dust and perching birds. It fulfills IEC 61672 Class 1 as well as the ANSI S1.4 Type 1 requirements. The outdoor microphone features a very low residual noise floor of only 16 dB(A) and supports precise and linear measurements up to 139 dBSPL.

The M2230-WP consists of the type approved M2230 Measurement Microphone mounted in the WP30 Weather Protection Kit. The WP30 Kit can thus also be purchased separately for customers who already have the M2230 microphone.

The upper section of the outdoor microphone is snap-on mounted and can therefore be easily removed by hand for convenient and quick calibration of the measurement microphone. The calibration parameters of the M2230-WP are stored on an internal electronic datasheet. Every time a microphone is connected to an XL2 Sound Level Meter, the microphone calibration values are automatically read from this datasheet, allowing the noise measurement to start without the customer having to first manually enter the microphone calibration values into the Sound Level Meter.

The outdoor case also delivers a professional solution for unattended noise monitoring. It protects the XL2 Sound Level Meter from severe weather conditions and offers generous space for batteries and further accessories. The connection cable to the outdoor microphone runs into the case through a rain-protected aperture.

The professional, mobile Noise Measurement Kit consists of the XL2 Sound Level Meter, the outdoor measurement microphone M2230-WP and the outdoor case. It forms a professional solution for environmental noise data acquisition in outdoor applications. This new kit from NTi Audio is now available for delivery.
