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
IEC 61672 class 1 as well as the ANSI S1.4 type 1 require-
ments for vertical sound incidence. For compliance with hori-
zontal sound incidence a frequency compensation is employed
in the associated XL2 Sound Level Meter.
The M2230-WP consists of an M2230 measurement micro-
phone enclosed in a WP30 weather protection kit.
