Other Parts Discussed in Thread: TLV320AIC3204,
Tool/software:
Hii TI,
I am working on a project that I need to measure dB in SPL at the speakers. I am using IMX6ULL processor, TLV320AIC3204 Codec and TPA3106D1 power amplifier. I am playing a 1KHz test tone in IMX6ULL processor and Measure the sound in dBSPL at the speakers. I set the HPL Driver gain to 10dB in the Codec and power amplifier gain is set to 36dB.
how much dB will I get at the Speakers.
Here one more point is that I need to measure the dB SPL levels at the Speakers from 60dB - 90dB by varying different gains at codec and power AMP. Did anyone have knowledge on this how to do calculations on this.
Regards,
N Eswara rao.
