Does air movement = Loudness

[DylanBeatz 10+ year member]

I'm not talking about numbers, im talking loudness to the ear.

Generally, if a system moves more air than another does that mean it will be louder?

Or is there really not an exact correlation?

No.

Loud=loud. Pressurizing the cabin

Loud=loud. Pressurizing the cabin

so you also say no? Wouldn't the cabin be more pressurized if it moved more air or no?

Yeah if pressurizing the cabin makes it loud wouldn't more air movement = loudness?

2 things:

If a system is playing a 20Hz song/continuous bassline, it won't be as loud as a 35Hz song/ continuous bassline. However, that system playing the 20Hz, is gonna create a looootttt of air vs,. the one with 35Hz.

Also depends upon the wattage that person has and the tuning as well.

this is where transfer function comes into play.... i think, dont quote me on that!!

(cabin gain)

for this example lets say that both cars are playing the same song and frequency. The one that moves more air will be louder to the ear?

No. Because the higher the song Hz, the louder it will be. Some people may/may not be able to hear 20Hz because our ears are made/designed (whatever you wanna call it) to hear certain frequencies. You may be able to feel it more than hear it.

@keep_hope_alive is an acoustic engineer, Hopefully he can explain a little more in depth.

Hope this makes sense to ya.

nope. I hardly move any air at 41hz but i do get a 153 with the window open.

This is not correct. It depends what your enclosure is tuned to and your vehicles cabin res freq. a car might peak lower and be way louder at 25hz then 35hz... The reason more air is being moved in your example is because you would be playing below box tuned and getting a lot more excursion thus creating more port velocity if built right and it's not unloading on you. In my truck 30-40hz is way more windy then 20hz.

This guy likes mids 30s and higher. He moves tons of air on them higher notes

That was insane! But I wouldn't expect anything less from 12 zv4s and 40k watts //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
