    Block Sound
AI Thread Summary
Blocking outdoor sound, particularly from loud music at venues like pubs and discos, presents significant challenges due to sound propagation in open air. Various forum participants discussed the limitations of existing soundproofing methods, which are typically effective indoors but not outdoors. Suggestions included the idea of creating a dome enclosure to contain sound, though practical implementation varies by location due to local regulations. The conversation highlighted the need for more innovative solutions, as traditional methods may not suffice in outdoor settings. The user expressed a desire to explore further options and share findings with the community.

ghalimoglu, Welcome to Physics Forums!

Don't worry about your English. Even with spelling mistakes and grammatical errors, what is important is that you communicate accurately.

Your question how to "block sound outdoor" is difficult for me to understand. Will you please explain your project in more detail? Describe exactly your conditions and your objectives. Thank you.

Cheers,

hi there,
welcome to PF :)

give us a lot more info please

what sort of sound ( frequency range)?,
from what type of source?
what are you trying to protect from this sound?
is there any level of the sound that is acceptable ?

there's a few Q's for you to answer initially

Dave
 
thank u daven and bobby for you concern

what sort of sound ( frequency range)?

i don't know the frequency range but just think you're in disco or pub and you're listining loud music.


what are you trying to protect from this sound?

i want to block the music outdoor places. ( disco or pub )
you know there's some rules for pub's or disco's. they have to turn off the the music after night.
not the disturb people.
so if i can block thw sound of these places they don't have to turn off their music after night.



i ll tell u about my project.

last summer while i was pub they stopped the music in 3 pm. so i told them why did you turned it off?
they asked, because of rules.
than i thinked about it if i block the sound in this kind of placeses they don't have to turnd the music off.
now its my purpose..

i searceh it there's some ways to block in room but there's is no way to block it in outdoor placeses.

ghalimoglu,

OK, now that we know a bit more :)

if the music source is outdoors, then there's not much you can do to stop it traveling out from an area. It could easily propagate a number of kilometres

In my country of Australia, the are local council laws governing the loudness of sound levels from club/pub bands and discos. Depending on the location of the club etc eg residential, commercial or industrial the maximum level they are allowed varies anything from ~ 90 to 105dB. Some have an additional restriction that the level has to decrease by another 5dB after a certain time at nite.

I actually build calibrated sound monitors for this purpose :) They will cut the power to the band or disco equip when the allowable limit is reached for a given period of time.
then the power is restored after a few seconds. the DJ or band don't like their gear switching on and off all the time so they get the message pretty quickly to "tone it down" haha

I have used these units in outdoor settings a few times, but short of permanently cutting the power, there isn't really much you can do to stop the sound propagating quite some distance

thnx for the answers.
@dave your solution is great but i can't do it in my country. :) actually, its temporal solution for me. even so thn u for you concern.

@bobby
solution in two languages :)

by the way
as you know sounds need a environment to move in the air.
so if i can make airless place then i can stop the sound.
but there's no way to do it
if i do , it wouldn't be outdoor :))

i'll keep go to search it.
if i found sth i'll apprise both of u ;)

thnk u again chav.
