In actual measurement situations, it takes a lot of time and effort if there are various measurement instruments when conducting in-situ measurements. We have developed an easy-to-use measurement which includes a multi-channel sensor amplifier and a dedicated portable measuring computer which has an intuitive touch panel operation. The A4 paper size instrument has a large display and an intuitive touch screen operation and can be used as data recorder, 1/3 octave band analyzer and FFT analyzer. The number of channels can be extended easily if a sensor amplifier is added. The instruments make it easier in outside in-situ measurements. We conducted noise measurement to examine and compare the new instruments and previous instruments especially in terms of time to setup and usage.
