Supply. What else is stop is a recently resurfaced concert venue a grateful kestrel sound isnt just down to skilled musicians acoustic technicians also play a major role. Youd think theyd check the acoustics by getting a musician to play an instrument think again. Shots fired in dresden score two apologist a woman has loaded a gun going on stage and is firing at into the air. While a man stands by listening attentively. Common and Maglite Lautenbacher are acoustic technicians in the last few years the call to a palace has undergone major renovations and the two were part of the project from
the outset no theyre testing to see if the acoustics are as good as they had hoped obviously they need an audience in its place they use specially made lengths of fabric a full concert hall sounds very different than an empty one. Firing the gun allows them to measure reverberation. But why dont they just use an instrument. There are several ways of Measuring Reverberations whats important is to mak
what exactly is an impulse response here s a floorplan of the stage circle installs the sound made on the stage is the impulse . it reaches the audience from the stage both via a direct route. and also by reflecting off the walls. this is the rooms response to the impulse and it needs to be uniform everywhere in the room. the hall is structured like a vineyard to ensure a consistent impulse response testing every single sound frequency would be too time consuming so the acoustic technicians bundle them into what are known as one third octave bands they sound like this. a deafening roar but there s a trick to it to understand what here s a crash course in sound and acoustics. sound is
octave. the sound waves frequency can be divided into sets with the help of an octave eight notes into what are called octave bands. then divide these into a further three sets one third octave bands the signal emitted contains the full range of a one third octave band as soon as the war dies out the technicians check to see if the full range of frequencies are being reflected equally by the room to hear their actual then we have the direct sound that s the easiest and fastest route from the source to the microphone we can see a vast amount of reflection from the. ceilings and combinations of all these responses reaching the ears. that since around music. that s the sweet spot the technicians measure it in every corner of the room the acoustics are perfect. let the music began.
