Hello,

We are seeking to precisely monitor the sound levels (dB) of the speech stimuli
we present to infants in our preferential looking laboratories. We wish to
report summary data such as the dB range and/or mean, and we think we might need
a remote microphone so that the measurement unit is external to the testing
booth where the sound levels are measured. 

We have encountered difficulties finding a suitable volume meter that will meet
our requirements. For example, we need to find a way of making sure that periods
of silence between stimuli do not get included in the calculation of the minimum
or average volume. Does anyone have any advice to offer?

Can anyone recommend a good sound level meter or a company that might supply
such meters (either UK based or with UK distributors)? We are particularly keen
to find a company or distributor that provides good technical support.


Many thanks,

Emily Mather and Suzy Styles
