Sound analysis of a smartphone/cell phone |
 |
-
Using the DS-3000 series Data station
and the LA-3560 Integrating sound level meter, acoustic
characteristics of ringtone from a smartphone/cell phone are obtained
while monitoring the sound pressure level.
-
Measure the sound pressure level of ringtone
by the LA-3560, and input the AC signal to the DS-3000
series. The DS-3000 series can analyze the AC signal
through FFT analysis, 1/1・1/3 octave analysis and trend
analysis of the specified frequency band. The power spectrum
max OA function of the DS-0321 FFT analysis software of the
DS-3000 series with octave function, allows spectrum
analysis at the maximum sound pressure of overall. The
output of A-weighted signal can be set by the LA-3560.
-
You can also use the MI-1235 (microphone),
the MI-3111 (preamplifier) instead of the LA-3560.
-
The OS-2740 Sound quality evaluation pack
(sold separately) can quantify the sound by using six
psychoacoustic parameters of [Loudness], [Sharpness],
[Roughness], [Fluctuation Strength], [AI], and [Tonality].
-
Use the sound insulating box to cut off the
disturbance sound.
