Infrasound noise may be monitored either external or internal to a dwelling to assess the impact of infrasound upon occupants of a dwelling.
External infrasound measurements
Infrasound levels may be measured at one or more external locations using an infrasound microphone located in an excavated hole in the ground with a suitable foam covering.
Internal Infrasound measurements
Infrasound noise levels may also be measured internally using one or more infrasound microphones in various rooms of a dwelling.
Microphones may all be connected to a SINUS Soundbook/Apollo style multi-channel data acquisition system so that all data is collected simultaneously and is synchronized.
Seismometers/accelerometers may also be connected to the data acquisition system, if desired.
A weather station may be installed external to the dwelling and input into the measurement system, if desired.
