Yes, it has to be, or you wouldn't hear them. Or at least at a close enough level that you can distinguish what they say. Either way, them shouting is adding to frequencies that are coming via the music and making those particular ones even louder, which is bad. Nightclubs are way too loud IMO. |
So you're saying the friend is then shouting louder than the music? If he/she was shouting louder than the music, everyone would be able to hear them. And by your observation of a particular frequency increasing in intensity by the words, some frequencies will be reduced and should make those ones quieter, which is good (?) ____________________ I'm Sam; Northern, Ginger, Lover

They're shouting louder than it sounds at your particular point. Going any further to say that some frequencies will cancel each other out is a bit complicated. You need to then look into the phase of the frequencies and take all the harmonics into account. Along with reflections and so on. The main reason you can hear them is because the voice has a distinctive pattern and frequency layout, very unlike that of music. They still need to kick out a fair racket to be heard, probably about 90dB@0.5m in your average club. The chances of the cancelling frequencies actually having an effect is more likely to just alter the voice you hear slightly.
The size of the source counts as well as the actual decibel level. |
I understand. I just used your general assumption that talking would amplify (perhaps not used in the correct sense) certain frequencies. So you're saying that it wouldn't have much of an effect then.
And also, that the friend is indeed, not louder than the music?
I said this because I stated earlier that the music needn't be louder than the wind noise - you confirmed this with "Or at least at a close enough level that you can distinguish what they say"
Also define, "size of the source". I presume you refer to the range of frequencies being fired out, not as in, "that speaker that's 10 feet tall is louder than the 2 feet tall one because size matters" ? ____________________ I'm Sam; Northern, Ginger, Lover

That's right. The primary idea behind playing music and wind noise, is that it's loud enough to be clearly distinguished, so that your mind focuses on the music rather than the wind noise. It doesn't have to be louder, but it helps and it's easy to achieve with decent isolation.

When you look at the creation of the sound.
So, a 6" drive unit putting out a 100hz tone, beside a 12" drive unit putting out a 100hz tone. If you set a microphone up, 1m directly in front of each and registered 100dB, the 12" drive unit would distort less, and offer a much larger dispersion of sound as they are moving more air. When you combine that with reflections, you will effectively hear it from further away/larger area. The larger drive unit will also have louder harmonics. ____________________ Biking history so far-

Good, cheers.

Genuinely interested; do you mean you would hear a 12" from further away than a 6" full stop or you would hear a clearer sound from the 12" than 6" ? ____________________ I'm Sam; Northern, Ginger, Lover
