Example 1
Referring to fig. 1, the embodiment provides a method for determining sound quality of a sound box, which specifically includes the following steps:
s1: acquiring a pink noise signal transmitted to a standard sound pressure level of a sound box to be tested through a signal generator;
s2: transmitting the pink noise signal to an audio analyzer to obtain a level value corresponding to the pink noise signal;
s3: acquiring a specific test signal transmitted to a standard sound pressure level of a sound box to be tested through a signal generator;
s4: transmitting the specific test signal to an audio analyzer to obtain a level value corresponding to the specific test signal;
s5: and setting the level value of the pink noise signal as a reference value, and comparing the level value of the specific test signal with the reference value to identify the sound quality of the sound box.
Note that the standard sound pressure level in this embodiment is 94dBSPL sound pressure value. The specific test signals involved in this embodiment include: a specific music signal, a sweep frequency signal, etc.
Firstly, before judging the sound quality of the sound box to be tested, a microphone calibrator is used for calibrating standard sound pressure of the judging system; secondly, the position where the sound box to be tested is placed is fixed, so that the distance between the sound box to be tested and the judging system is kept at a position where signal transmission can be realized, and the sound box to be tested can be directly placed at the position conveniently when a plurality of sound boxes to be tested are judged, so that test errors are reduced. Based on this, referring to fig. 2, the following steps are also required to be performed before step S1 is performed:
s01: receiving a sound signal of a standard sound pressure level sent by a microphone calibrator for calibration;
s02: obtaining the distance between the sound box to be tested and the sound box to be tested so as to fix the position of the sound box to be tested;
s03: and sending a volume adjusting instruction to the sound box to be measured so as to enable the sound box to be measured to adjust the volume to the maximum value.
In order to determine the sound quality of the sound box at the same sound pressure level, the pink noise signal and the specific test signal acquired by the determination system should be at the same standard sound pressure level. Based on this, referring to fig. 3, for the specific procedure of "transmitting the above pink noise signal to the audio analyzer to obtain the level value corresponding to the above pink noise signal" involved in step S2, it includes:
s21: detecting whether the sound pressure of the pink noise signal is at a standard sound pressure level; if yes, go to step S22; if not, executing step S23;
s22: transmitting the pink noise signal to an audio analyzer to obtain a level value corresponding to the pink noise signal;
s23: transmitting an adjusting instruction containing the level value of the pink noise signal to the sound box to be measured so that the signal generator adjusts the level value of the pink noise signal based on the adjusting instruction forwarded by the sound box to be measured; step S21 is repeatedly performed.
Namely: the judging system judges the sound pressure of the pink noise signal transmitted by the sound box to be detected, and if the sound pressure of the pink noise signal is at a standard sound pressure level (namely 94dBSPL sound pressure value), the judging system sends the pink noise signal to the audio analyzer for analysis and processing; the audio analyzer analyzes the pink noise signal to obtain a level value corresponding to the pink noise signal. If the sound pressure of the pink noise signal is not at the standard sound pressure level, the judging system sends an adjusting instruction containing the level value of the pink noise signal to the sound box to be detected, and the adjusting instruction is further transmitted to the signal generator through the sound box to be detected; thus, the signal generator adjusts the level value of the transmitted pink noise signal so that the sound pressure of the transmitted pink signal is at the standard sound pressure level.
It should be noted that, the pink noise signal according to the present embodiment refers to a signal transmitted by the signal generator, and the pink noise is the most common noise in nature, and is mainly distributed in the middle-low frequency band, and is commonly used for sound of acoustic test.
It should be noted that, referring to fig. 4, for the specific process of "sending the specific test signal to the audio analyzer to obtain the level value corresponding to the specific test signal" in step S4, the specific process is as follows:

s42: transmitting the specific test signal to an audio analyzer to obtain a level value corresponding to the specific test signal;
s43: transmitting an adjusting instruction containing the specific test signal to the sound box to be tested so that the signal generator adjusts the level value of the specific test signal based on the adjusting instruction forwarded by the sound box to be tested; step S41 is repeatedly performed.
Namely: the judging system judges the sound pressure of a specific test signal (such as a specific music signal, a sweep frequency signal and the like) transmitted by the sound box to be tested, and if the sound pressure of the specific test signal is at a standard sound pressure level (namely 94dBSPL sound pressure value), the judging system transmits the specific test signal to the audio analyzer for analysis and processing; the audio analyzer analyzes the specific test signal to obtain a level value corresponding to the specific test signal. If the sound pressure of the specific test signal is not at the standard sound pressure level, the judging system sends an adjusting instruction containing the level value of the specific test signal to the sound box to be tested, and the adjusting instruction is further transmitted to the signal generator through the sound box to be tested; the signal generator will thus adjust the level value of the transmitted specific test signal such that the sound pressure of the transmitted specific test signal is at the standard sound pressure level.
It should be noted that, in the method for determining sound quality of a sound box according to the present embodiment, the pink noise signal is used as a reference signal so as to be compared with other specific test signals to determine the sound quality of the sound box, and a plurality of sound boxes to be tested can be respectively determined to obtain a level value corresponding to the specific signal and a level value of the pink noise signal, so that the sound quality of each sound box to be tested can be identified through the comparison between the corresponding level values, and a test error caused by subjective judgment of the sound quality of the sound box by human ears is avoided.
