All Right, Tell Me How To Use This Machine…

The kit that you have received is a sophisticated device which utilizes two different tools – a digital recording device and a sound pressure meter. Although it is not important to understand the internal workings, it is important for you to know that you are going to be doing two things at the same time – measuring and recording. These two tools need to be turned on and off individually. We will refer to the kit as the RTSK (Remote Sound Testing Kit) below.

As this system was being developed, we did our best to predict what kind of situations we would be presented with and hope to have developed a set of instructions that work with the greatest number of situations. Because there was no way for us to write specific instructions for ALL situations, please understand if we add a few steps here and there to gather the best information possible per the problem or problems that you are experiencing. Keep in mind, the more valid the information gathered, the more accurate the model and results.

We understand that the situations and problems that you are experiencing is unique and we will be developing a plan of gathering data that is unique to your environment. We ask that the measurements are taken during a time that is representative of the environment in which the problem is being experienced.

Please Note: We will need images from all data collection points just before the data is collected. You will need a digital camera or similar image capturing device for this. All pictures should be taken toward the center of the room. If the area is sensitive and this is not possible, please contact us.

Remote Sound Testing Device
  1. Precautions

    • Please read through all of the instructions below before beginning the measurements.

    • The accuracy of the analysis is in part dependent upon positioning the recorder at the positions prescribed in the measurement plan. Use care when positioning and orienting the recorder.

    • **PLEASE NOTE** Your body can create an acoustic “shadow” resulting in inaccurate sound measurements. When taking the measurements, do your best to have your body positioned so as to minimize this shadowing effect from all nearby sources.

  2. Carefully thread the monopod to the bottom of the Remote Sound Testing Kit (RSTK). Do not force the threaded stud into the threaded hole.

  3. Go to the first measurement location specified in the provided measurement plan.

  4. On the left side of the machine, Turn on the Remote Sound Testing Kit (RSTK) by pressing and holding the PWR button for 3-5 seconds (the display will light up orange).

  5. Press the SPL button once.

  6. Using the supplied monopod to help support and position the kit at the correct height (3 feet above the ground), hold the RSTK so that the perforated metal face is pointing towards the ceiling.

  7. Press the REC button once (the edges of the button will flash red). The RSTK is now in standby mode. Write down the name of the current record file on the data log form. This information will be shown on the amber LCD display (e.g. DR000003.wav).

  8. On the data log form, note the date, time and measurement location description.

  9. Capture one digital image of this location, pointing your camera toward the center of the room.

  10. Press the REC button once more (the edges of the button will turn to steady red).
    ***The RSTK is now recording.***

  11. Allow the RSTK to record for 90 seconds; then press the STOP button.
    Note: If something affects the quality of the recording (e.g. ringing phone, radio call, a sneeze, talking), please add a note in the comments of the data collection sheet. (e.g. phone ringing - disregard). If this happens, press STOP and repeat steps 6-10.

  12. On data log form, record “SPL” number that you estimate to be the average or most frequently appearing number. (Does not have to be exact.)

  13. Proceed to each remaining measurement location, repeating steps 6-12.

To Shut Down the RSTK
  1. Press and hold the SPL button until the screen reads “OFF

  2. Press and hold the PWR button until the screen turns off.

  3. Carefully unscrew the monopod and return both to the protective case.

If you have one machine (or a handful of machines) that are particularly loud or a few that you would like to focus on, we may ask that you gather data at multiple points around this machine and make a specific note about these measurements on the data log form.
