  • Page 13: Introduction

    “Never before has a noise dosimeter been so accomplished yet so affordable, making your measurements more accurate and reliable than ever before”. To get started quickly with SV 104BIS, the first part of the manual describes basic noise dosimetry information followed by a guide to setting up the dosimeter and running measurements.

  • Page 14: Sound Pressure

    SV 104BIS User Manual OUND PRESSURE The human ear responds to audible sound pressure levels in the range from 20 μPa (hearing threshold) to 20 Pa (pain threshold), resulting in the enormous scale 1:1,000,000. Since using such a large arithmetic scale is not practical, a logarithmic scale in decibels (dB) was introduced which is also in agreement with physiological and psychological hearing sensations.

  • Page 15: Applications

    One of the most desirable SV 104BIS feature is the unique data logging function that stores significant number of noise parameters at regular intervals and superimposed random vibration shock or audio events during...

  • Page 16: Measurement Procedures

    This makes checking for different regulatory bodies’ compliance and ensuring if hearing conservation programs are needed definitely easier than ever before. SV 104BIS answers all the important questions such as WHEN and HOW did the noise exposure appear? The data logging measurements can be started immediately, or they can be pre-programmed in advance so that measurement run can begin and end automatically at a pre-set start and end time without the need for any onsite supervision.

  • Page 38: Calibration

    ALIBRATION The SV 104BIS dosimeter is offered with the dedicated ST 104B MEMS microphone with ½” housing. The instrument is factory calibrated with the supplied microphone for the standard environmental conditions. Because the microphone sensitivity is a function of the temperature, ambient pressure and humidity, the absolute calibration of the measurement channel should be performed locally.
  • Page 39 (the default expected value of the Calibration Level set by the manufacturer of SV 104BIS is equal to 114 dB). 3. Switch on the calibrator and wait ca 30 seconds for the tone to stabilise before starting the calibration measurement.
