Intelligent Network Measurement System

CITY CONTROLEvent Acoustics has developed theMeTraoPro-ActiveSoundLevelNetworkwhich measures noise in severalproperties at once (internal) combiningthe data with measurements from theenvironment (external). This offers anintegratedsolutionforurbanareaswheremultiplesimultaneoussourcesrequireacollectivecentralizedapproachtoadheretothenoiseregulations.TheMeTrao systemsare ideal for bars/restaurants, but also at one or moresurrounded buildings (like houses).The systems send their data throughan internet connection and send it to acentraldatabase.A MeTrao city-monitoring project inRotterdam has reduced neighbourhoodnoisecomplaintsby60%inthepasttwoyears.

EVENT CONTROLMeTrao was designed from real lifeexperience gained from managing thesoundlevelsofvariouslarge-scaleDutchandBelgianfestivalssuchasNorthSeaJazzandLaundryDays.EventAcousticsdeveloped the system’s latest usefulfeaturesbasedonchallengesthataroseatsuchevents.Whatisuniqueaboutthesystem is its level of sensitivity – it canhighlight which stage of a multi-stagefestivaliscausingtheproblemandinsomecases what frequencies or combinationoffrequenciesarecausingtheregulationnoise levels tobebreached.Thismeantany issue can be pinpointed and solvedattheexactsource,ratherthanchangingtheoverallvolumelevelsofall20stages.

VENUE CONTROLMeTrao is ideal for monitoring andcontrolling the sound levels in clubs,theatres and halls. The system hasincorporated feedback from pophalls such as Tivoli Utrecht, ParadisoAmsterdam, de Vooruit Gent and thedesiredcapabilitiesofmanyinternationalsound engineers.Not only is it possibletomonitor,predictandregisterthesoundlevelsforconcertsandtheirenvironmentonsite,buttheMeTrao’swebbasedandmobileversionsallowsuserstomonitoravenue’sdataremotely,sothetechnicalmanagerofatheatrecankeepaneyeonitfromthecomfortoftheirsofa.

CAUTIONS

There is not much to worryabout.Themeasuringpoint intheimmediate vicinity has discoveredmusic or other sounds, but thenoiseisn’texceeded.

Action:None,butbeaware!

TAKE LEVEL DOWN

The regulation levels have beenbreached. The measuring pointin the immediate vicinity hasdiscoveredmusicorothersoundswhich are beyond the noisestandards.

Action: Check that windowsand doors are closed to preventthe noise escaping. Lower thevolumeandbasstonesandcheckthe frequencies at the MeTraowebface.
