Outdoor Microphone M2230-WP

Introduction

The M2230-WP is a weather-protected microphone solution

for the XL2 Sound Level Meter allowing acquisition of environ-

mental noise data in outdoor applications. The corrosion-free

polymer housing, wind screen, water-repellent membrane and

bird spike provide excellent protection from rain, wind, dust

and perching birds.

The frequency response of the M2230-WP fulﬁlls the class 1

requirements of IEC 61672 and ANSI S1.4 for vertical sound

incidence. Frequency compensation is employed in the associ-

ated XL2 Sound Level Meter for compliance with horizontal

sound incidence.

The M2230-WP consists of an M2230 measurement micro-

phone enclosed in a WP30 weather protection kit.
