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
power at 1W, then test the frequency response 1m away from the
speaker.
2. Sensitivity
Use full range Pink noise which has been modified using an EQ
curve to test the speaker in the anechoic chamber, increasing the
signal to make the speaker work at its rated impedance and set the
power output at 1W, then test 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 speaker in the anechoic chamber , increase the
signal to make the speaker work at its maximum power output
level, then test the SPL1m 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.
