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 ,
i n c r e a s e t h e s i g n a l t o m a k e t h e s p e a k e r w o r k a t i t s
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 of100 hours,
the rated power is the power when the speaker will show
no visible or measurable damage.
