I have continuous A-weighted sound pressure level (SPL) values at 1 minute time resolution (LAeq,1min). I would like to calculate LAeq SPL at half-hourly and hourly resolutions using these values. Can someone suggest on how this could be achieved?

  • $\begingroup$ average over 30 minutes or 60 minutes or take the max value in 30 minutes or 60 minutes. $\endgroup$

  • $\begingroup$ No, because if I do it in my program you will want it in another. So, now you have the idea you can implement it. $\endgroup$

Leq represents the time weighted average. So isn't it just:

$$Leq (hour) = \frac{1}{60}\sum_{n=1}^{60}Leq(minute_{n})$$
