5.1.4 Calibration of Volume
ºѧ§

The Competitor will suggest the volume to be listened at by the sound judges.
觢ѹ 繼Ѻ§ÿѧ

The Judges should use this Volume! Only in case that the suggested Volume
is too loud (see Point 5.1.4 in the Rulebook, more than 80dB),
the Judges have to take a measurement to correct the Volume.

èлѺѧ дѺ§觢ѹѺ ѧԹҹ!!! (Թ 80 ഫ)

If the Competitor doesn't suggest a Volume, follow these Steps:
ҡ觢ѹ ѺдѺ§ ӵ鹵͹ҹ

The voice level of the passenger side judge should be as loud as we talk in meetings.
дѺ§ͧ ҧ еͧѧҡѺ¡ѹ㹡ûЪ

Not like talking to your girl friend.
͹Ѻ¡ѺΌͧس (ѹԡ ѧ ѹ... ѧ Ѻ)

The music should sound louder than background music or music suitable for conversation.
§ еͧѧ §ẤǴ дѺ§Ѻʹ

Should be loud enough to be able to hear all the details of the music, in full body.
ͧѧͷöԹ´§ Թ§

The 2 judges should be able to clearly hear each other when they talk a little louder than normal.

A LITTLE THEORY ABOUT SOUND
ɮ ǡѺ§ Ѻ

When judging depth or width we must take into consideration certain things about sound.
ͷӡ觢ѹ ҹԵԧ֡ ԵԧйҺ
觢ѹеͧ Һ֧ѡоԨó ǡѺɮ§ҹ㨡͹ФѺ

1. The speed of sound in dry air of 20 degrees C, is 1235Km/h
1. Ǣͧ§ҡ س 20 ͧ ҡѺ 1,235 ./.

2. A sound, sounds louder by 6db for every half distance we move closer to it.
2. §дѧ 6 ഫ 觡Դ§ ء ˹觢ͧзҧ
觡Դ§ҧҡ 10 ѧ 90 ഫ Թ 5 ѧ 96 ഫ

3. A sound, sounds lower by 6db every time we double our distance from it.
§ŧ 6 ഫ ҧ͡ҡ觡Դ§ ء ˹觢ͧзҧ
ѡɳФ ѹѺ 2

In our case we stay at the same position, but we have the sound moved away, which is basically the same.
㹡óբͧÿѧ蹹 Ҩ觡Ѻ §ա͹͡ ѡǡѹѺ

We move this sound source to 200cm from the listener. We have 78db at the listening position
ҡ͹˹觢ͧ觡Դ§͡ա 200 . ҡѧ ҨԹѧ 78 ഫ ˹觷ѧ

We move this sound source to 250cm from the listener. We have approximately 76,5db at the listening position FAR LEFT
ҡ͹˹觢ͧ觡Դ§͡ 250 . ҡѧ ҨԹѧҳ 76.5 ഫ ˹ Far Left

We move this sound source to 350cm from the listener. We have approximately 73,5db at the listening position EXTREME FAR LEFT
