Speaker testing method
1. Frequency response
Use Pink noise to test the speaker in the anechoic room, adjust the
level to make the speaker work at its rated impedance and the power
output is 1W, then test the frequency response 1m away from the
speaker.
2. Sensitivity
Use full range Pink noise which was modified by EQ curve to test the
speaker in the anechoic room, enlarge the signal to make the speaker
work at its rated impedance and the power out put is 1W, then test
the sensitivity 1m away from the speaker.
3. MAX.SPL
Use full range Pink noise which was modified by EQ curve to test the
speaker in the anechoic room, enlarge the signal to make the speaker
work at its instant pow er output level, then test the SPL 1m away
from the speaker.
4. Rated Power
Use the pink noise according to IEC#268-5 to test the speaker, enlarge
the signal for continuous 100hours, the rated Power is the pow er when
the speaker will not incur hot damage or mechanics damage.
