The Acoustimeter is a user-friendly accurate RF measurement instrument
which provides LED light and LCD text displaying peak, peak hold, and
average levels of radio frequency electromagnetic fields, covering the
spectrum from TETRA all the way up to and beyond the 5.6 GHz WiFi and
WiMax frequencies. It has a digital readout which is sensitive to 0.02
V/m and a sound output enabling you to hear the signal modulation. These
features make the instrument the most useful one available to even
those with severe electrosensitivity.
The Acoustimeter has been designed to enable you to make a quick and
informed judgement regarding the level and nature of microwave signals
in your environment. It is a broadband instrument that accurately
measures the totality of the radiation in the range 200 MHz to about
8000 MHz (8 GHz), which covers the frequencies used by most modern
communication systems encountered in our everyday environment. The
Acoustimeter was designed using the experience gained from many years of
practical RF and microwave measurements.
The readings are shown on both an LCD display and two series of
graduated LED lights. The LEDs update rapidly, and allow you to quickly
gauge the levels in an area and find any hot-spots. The LCD display
offers high accuracy with a lower update speed, giving you time to take
note of the readings. It also has a speaker (and audio output socket for
headphones or to feed to an audio recorder), allowing you to determine,
with a small amount of practice, what type of device is creating the
levels that are present. Sound samples are available on on this page to
help you identify what kind of signal your Acoustimeter is measuring.
The sounds made by different transmitters can change with time, so these
are meant as a rough guide only. If you are subject to a number of
sources of RF, the sounds may intermingle and be less easily identified.
In areas where there is virtually no modulated microwave radiation
(below the level of 0.02 V/m that the Acoustimeter is designed to
detect), it is possible, with the volume turned fully up, to hear
faintly some background clicking. This is from internal workings of the
Acoustimeter and is not related to any external signal, and is therefore
of no concern.
