noise measurement kit / exterior
The WK1, manufactured by Pulsar Instruments, is a short term outdoor noise measurement kit that is only intended for measurements that are for relatively short periods i.e. up to a day or overnight. The pre-amplifier and microphone from the sound level meter itself are fitted within the ‘waterproof’ mounting system complete with windshield and bird-spikes. Rain or even heavy fog, can make using a normal sound level meter outside for long periods impractical, as moisture can damage the microphone capsule and in extreme conditions the instrument itself. Environmental noise monitoring usually takes place outside and the sound measurement device is therefore subjected to various weather conditions. The 10 meter cable coming from the microphone assembly is connected to the extremely robust weatherproof carry case which protects the instrument, power supply and accessories.
