The sound quality of the speaker depends on what
01
Sound source characteristics
The sound quality of a speaker depends on many factors, among which the characteristics of the sound source are an important part. Sound source characteristics include sound pressure, frequency, spectrum, etc. These parameters will affect the sound quality of the sound. Different sound source characteristics will bring different timbre effects, such as treble, bass, restoration, distortion, etc. Therefore, a better sound quality experience can be obtained by selecting suitable sound source characteristics.
02
Signal characteristics of audio equipment
The sound quality of an audio system depends on many factors, such as the characteristics of the sound source, the signal characteristics of the audio equipment, the sound field characteristics, and the auditory characteristics. Among them, the signal characteristics of audio equipment include distortion, frequency response, dynamic range, signal-to-noise ratio, transient characteristics, stereo separation, etc. To evaluate the sound quality, you need to listen to various sound effects in a relatively standard environment. Therefore, audio enthusiasts need to understand the signal characteristics of audio equipment in order to better evaluate the sound quality and provide a better listening experience.
03 Sound field characteristics
The sound quality of a speaker depends on the characteristics of the sound field. The sound field characteristics include direct sound, early reflection sound, reverberation sound, interaural correlation coefficient, reference vibration and sound absorption rate, etc. These characteristics determine the propagation path and frequency range of sound in the speaker, thereby affecting the performance of sound quality. A good sound field characteristic can make the sound of the speaker more realistic and shocking, so that the audience can feel the realism of the music. Therefore, when evaluating the sound quality of the sound, it is necessary to consider the influence of the sound field characteristics.
04 Auditory characteristics
The sound quality of a speaker depends on its auditory characteristics. Hearing characteristics include loudness curve, audible range, various hearing sensations, etc. Evaluators need to listen to various sound effects in a relatively standard environment to ensure that the sound quality meets the requirements.
5. Balance
The sound quality of the stereo depends on the sense of balance. The sense of balance refers to the correct proportion and phase of the output power between the left and right speakers, the main speaker and the auxiliary speakers. If the sound image is sometimes shifted and uncoordinated, it's not good sound quality. Because the sense of balance is good, the consistency of the left and right channels of the stereo is good, and the sound image is normal. If the sound image is sometimes shifted and uncoordinated, it's not good sound quality. Therefore, the sense of balance of the sound is one of the important factors affecting the sound quality.
06 Signal to Noise Ratio
The sound quality of a speaker depends on the signal-to-noise ratio. The signal-to-noise ratio refers to the ratio of the audio system's replay sound to the sound source software and the new noise generated by the entire system. Generally, this index is detected by the logarithmic ratio of the rated output power of the replay signal to the system noise output power when there is no signal input. expressed in decibels (dB). Generally, the signal-to-noise ratio of the audio system needs to be above 85dB. The higher the signal-to-noise ratio, the higher the quality of the equipment, and a good speaker can reach ≥100db. But the price is also higher. Generally, the signal-to-noise ratio of 2.0 speakers can reach 80db, and a larger one is also acceptable. X.1 speakers are ok as long as they are greater than 75db.
07 Loudness
The sound quality of a speaker depends on its loudness. Good sound quality sounds suitable and comfortable. It is especially reminded that when distinguishing sound quality, you should choose an excellent sound source as the program source for audition, and it is more beneficial to choose the content you are familiar with for testing sound quality. Good speakers have very low distortion, so they will sound great no matter the volume. Even if the volume is turned up to full power, the speaker explodes earth-shatteringly, and the low frequency rolls like midsummer thunder, it will only make you feel close to nature, lifelike and even terrifying shocking force, but it will never make a cracking sound that will make you escape from your ears .
08 power amplifier
Sound quality depends on the amplifier. The power amplifier is the core part of the audio system, which is responsible for amplifying the weak electrical signal from the signal source and driving the speaker to produce sound. The greater the power of the power amplifier, the lower the distortion and the better the sound quality. In addition, the power amplifier's control over the speaker is also very important, and the damping coefficient and power rise time will also affect the sound quality. Therefore, the power amplifier is the key to the sound quality of the sound.
