Eid se phly ho ga ya baad me....

meet me ahmed ,
hmm my idea is to play Single notes on SPL setup
it would be better , what SPL meter will that number for longer enough to
notice and write somewhere

there is still 1 thing left , meet me sometime discussion / experiment left
probably first we have to play 20~120hz
separately on each sound system ...

idea 1 : make some track common ,like BME Click , Throw it Up
i am going to take out their frequency notes and get single note from webpage
that will be played on system during SPL check

BME Click
35hz 1st note
43hz 2nd note
40hz 3rd note
in song or system it doesn`t remain constant db , have fluctuating DB on notes
during record each notes will be bumping ( hard to detect by ears ) that will make DB meter reading bump and bump

so i wanna , I am gonna use 35hz ,40hz and 45hz bass Test tone on each system , a user will turn up volume to max , there db of these notes will be meter much constant ( i have experimented alot for years)
so we can note db meter recording , there will be 3 notes and 3 different dbs on each notes
then we will average that
to make final answer

[geforce]

oh yes , i got firm holding settings of DB
now make it final (i have 30hz,32hz,33hz,35hz,36hz,40hz,43hz,45hz,50hz)

35hz , 40hz , 45hz
cause most of the track lies in between 35hz and 45hz
Low to High will be finalize , even it will be done in fair means , if some one says i have 35hz tuned enclosure or 37hz or 38 or even 40hz i have answer

for those who think low tuned enclosure have flat response (yes it have , and high have peak )
E.g just an e.g assume it
35hz tuned enclosure 1Kwrms , tones ( 35hz ,40hz,45hz)
output
123db @ 35hz , 127hz @ 40hz , 124 @ 45hz

38hz tuned enclosure 1Kwrms , tones ( 35hz ,40hz,45hz)
120db @ 35hz , 125db @ 40hz , 130 db @ 45hz

38hz defeated in low frequency
35hz defeated in high frequency

Taking Average , to final value
and the avg number will be final db spl

i see sum suspence building, it better be termlab

[geforce]

yaar Termlab cost 600$
even Industrial Sound Meter like 60~300$ even more with different weightings ABC/ flat
so its not an easy task to get that + just for that purpose only , during test it gets in use , while use to kept in store + these devices needs to be calibrated as well on some duration

even a human cant judge which hits louder exactly , between 139.2 or 140.1db
so my idea , No cost , no nothing to do , i only needs 1~2 mins to test out SPL per System

honestly , its will separate out WATER from MILK
this software ( with my current selected settings ) can judge how much Sound pressure is inside your car
how ever its not close or exact to term lab accurate

but main point is between US (our different systems some type R , pioneer ,splx , kenwood , even Solo X:P)
it will judge honestly which gets loudest,
i will make sure people system make more numbers as a true SPL competition ( i may ask peoples to put ur hands tight on rattling/vibrating parts )

Dude. Plz tell me... k venue kon sa select kia hai.... Expo or Hill Park

@ gman

alot depends upon the mic, mb ur mic wont even go accurate above 140db

i suggest 600$ is no big deal 50-60gz is nothing if every member contributes a 1000rs.

i can gurantee a 10-15g contribution from my city. Get it and step up the game for real

or we shuld ask yousaf to get as he is not worried abt price tags hahah

Yes it have limit of sensation
if i can set mic sensitivity level it can even notice spl 140+
although it needs to be calibrated with real SPL

yaar , JL Audio have some software for Iphone users to check out spl
http://itunes.apple.com/us/app/jl-audio-tools/id388648626?mt=8

[durty_riz]

yes iphone has that software.. blackberry geeks will soon come out with the same software.. but the prob isnt with the software, its the mic. Normal mic wont even go above 50dbs let alone the caliberation prob.
Normal mics arent made for metering pressure levels but made for high pitch noises as human vocal cords. they can however meter your tweets to some extent but definitely not ur subs.

even the galaxy cm140, which is the only meter that is acceptable by the US courts after TL is also -+2dbs from accuracy let alone the normal mics.

Anyhow we are still trying to find a suitable option so please be patient.

Thanks
Riz

find a sponsor and get termlab. simple as that.

iv got a plan....
