Despite losing an LED during the presentation set up overall it went really well. (I said environment way too much)
The questions that we were asked were both informative of our product and presenting, concerning both the technical elements that we had dismissed in our development as well as queries pushing the importance of sound and how people would react in an environment that increases focus on the awareness of the sound environment.
One question that was slightly out of field was a query of volumes by motorways. Naturally this is in an area of unknown or unspecified factors, sound insulation, building materials, sheltering, which changes the reception of sound itself. Being aware of the environment in relation to sound also means being aware of it in terms of location and what that area comprises of. Different materials provide different levels of insulation against the elements, sound inclusive.
The first step to bettering the environment you’re in may start with being aware of sound, but continues with the investigation and maturing of the environment through your influence.
That said the decibel values for living by a motorway, unabsorbed by plantlife, barriers or otherwise, would be very high, and well beyond recommendable exposure levels for a few hours.
