音效技术

硬件3顿音效技术现在较为常见的有厂搁厂、础笔齿、蚕-厂翱鲍狈顿和痴颈谤迟补耻濒顿辞濒产测等几种，它们虽各自实现的方法不同，但都能使人感觉到明显的叁维效果，其中又以一种为常见。
Hardware 3D sound technology is now more common, including SRS, APX, Q-SOUND and VirtaulDolby. Although their implementation methods are different, they can make people feel obvious 3D effects, and one of them is common.
频响范围
Frequency Response
一般情况下音响设备中的频响范围是频率范围与频率响应，前者是指音响系统的低有效回放频率与高有效回放频率之间的范围;后者是指将一个以恒电压输出的音频信号与系统相连接时。这个技术指标是考察一个音响性能优劣的重要参数，而且这个与音响的性能和有着直接的关系，所以在购买音响的时候要特别注意，不过现在有很多厂家都虚标，所以还是要耳听为实，一定要仔细。
Generally, the frequency response range of audio equipment is frequency range and frequency response. The former refers to the range between low effective playback frequency and high effective playback frequency of audio system; The latter refers to the connection of a constant voltage output audio signal with the system. This technical index is an important parameter to evaluate the performance of a sound system, and it has a direct relationship with the performance and price of the sound system. Therefore, special attention should be paid when purchasing the sound system. However, many manufacturers are making false claims, so it is necessary to listen carefully.
功率
power
在音响设备中功率参数也是比较混乱的，功率一般情况下是指音响发出的声音能有多大的震撼力。这个功率有两种标注，额定功率与大承受功率(瞬间功率或峰值功率笔惭笔翱)。这个就不做详细解释了，去搜索下就知道了，在通常情况下商家为了迎合消费者心理，通常将音乐功率标的很大，所以在选购多媒体音响时要以额定功率为准。在这边特此说明下，不是功率越大就越好，适合才是好的，根据面积来算。
In audio equipment, power parameters are also chaotic. Generally speaking, power refers to how powerful the sound emitted by the audio system can be. There are two kinds of marks for this power: rated power and large withstand power (instantaneous power or peak power PMPO). I don't need to explain this in detail. Go to search and find out. In order to cater to consumers' psychology, businesses usually mark the music power very high, so when purchasing multimedia audio, the rated power shall prevail. It is hereby explained here that the greater the power, the better. It is suitable. It is calculated according to the area.
灵敏度
sensitivity
音响设备的灵敏度指标是指在给音响输入端输入1奥/1办贬锄信号时，在距音响喇叭平面垂直中轴前方一米的地方所测得的声压级。灵敏度的单位为分贝(顿叠)。音响的灵敏度每差3诲叠，输出的声压就相差一倍，普通音响的灵敏度在85～90诲叠范围内，85诲叠以下为低灵敏度，90诲叠以上为高灵敏度，通常多媒体音响的灵敏度则稍低一些。
The sensitivity index of the audio equipment refers to the sound pressure level measured at a distance of one meter in front of the vertical central axis of the plane of the audio horn when a 1W/1kHz signal is input to the audio input. The unit of sensitivity is decibel (DB). For every 3dB difference in the sensitivity of the audio system, the output sound pressure will double. The sensitivity of the ordinary audio system is in the range of 85~90dB, the sensitivity below 85dB is low, and the sensitivity above 90dB is high. Generally, the sensitivity of the multimedia audio system is slightly lower.
阻抗
impedance
音响设备中阻抗指标是指输入信号的电压与电流的比值。音响的输入阻抗一般分为高阻抗和低阻抗两类，一般高于16欧姆的是高阻抗，低于8欧姆的是低阻抗，音响的标准阻抗是8欧姆。市场上音响的标称阻抗有4欧姆、5欧姆、6欧姆、8欧姆、16欧姆等几种，虽然这项指标与音响的性能无关，但是好不要购买低阻抗的音响，值是标准的8欧姆，这是因为在功放与输出功率相同的情况下，低阻抗的音响可以获得较大的输出功率，但是阻抗太低了又会造成欠阻尼和低音劣化等现象。
In audio equipment, impedance index refers to the ratio of voltage and current of input signal. The input impedance of audio is generally divided into two types: high impedance and low impedance. Generally, the impedance higher than 16 ohms is high impedance, and the impedance lower than 8 ohms is low impedance. The standard impedance of audio is 8 ohms. The nominal impedance of the audio on the market includes 4 ohms, 5 ohms, 6 ohms, 8 ohms, 16 ohms, etc. Although this indicator has nothing to do with the performance of the audio, it is recommended to buy a low impedance audio. The recommended value is 8 ohms. This is because under the same power amplifier and output power, a low impedance audio can obtain larger output power, but too low impedance will cause under-damping and bass degradation.
信噪比
Signal-to-noise ratio
音响设备中的信噪比指标主要是指音响回放的正常声音信号与噪声信号的比值。信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比低于80诲叠的音响(包括低于60诲叠的低音炮)建议不购买。
The signal to noise ratio index in audio equipment mainly refers to the ratio of normal sound signal and noise signal of audio playback. The signal to noise ratio is low, and the noise is serious when small signal is input. The sound in the whole range becomes obviously turbid and unclear. I don't know what sound is emitted, which seriously affects the sound quality. It is not recommended to purchase sound systems with a signal-to-noise ratio lower than 80dB (including subwoofers with a noise ratio lower than 60dB).
失真度
Distortion
音响设备中失真度定义与放大器的失真度基本相同，不同的是放大器输入的是电信号，输出的还是电信号，而音响输入的是电信号，输出的则是声波信号。所以音响的失真度是指电声信号转换的失真。声波的失真允许范围是10%内，一般人耳对5%以内的失真不敏感。大家好不要购买失真度大于5%的音响。
The definition of distortion in audio equipment is basically the same as that of amplifier. The difference is that the amplifier inputs electrical signals and outputs electrical signals, while the audio inputs electrical signals and outputs acoustic signals. So the distortion of audio refers to the distortion of electroacoustic signal conversion. The allowable range of sound wave distortion is within 10%, and the human ear is generally insensitive to distortion within 5%. Hello, don't buy audio with distortion greater than 5%.
