Hi all, I would like to ask a question to the masters here.
Suppose I have two siren driver speakers as each one is 50 dB connected parallel and 100 dB in total.
And there is one unique siren driver speaker as 100 dB.
Will be a difference for audible sound level in 3 km away or will both systems give the same effect ?

Thanks in advance for your kind comments.

Regards,
ilker

Sound measured in dB is a logarithmic scale.
50 dB + 50 dB does not give 100 dB.
50 dB + 50 dB gives 53 dB.
