Speaker Testing Method
1. Frequency Response
Use pink noise to test the speaker in the anechoic chamber,
adjust the level to make the speaker work at its rated impedance
and set the output
1m away from the speaker.
2. Sensitivity
Use full range pink noise which has been modified using
an EQ
curve to test the
Increasing the
impedance and set the
sensitivity 1m away from the speaker.
3. MAX.SPL
Use full range pink noise which has been modified using
an EQ
curve to test the
increase the
mum power output level, then test the SPL 1m away from
the speaker.
4. Rated Power
Use pink noise to the IEC#268-5 standard to test the speaker,
increase the signal for a continuous period of 100 hours,
the rated power is the power when the speaker will show
no visible or measurable damage.
