What is sound distortion? What is speaker distortion?

Sound distortion is a phenomenon we often encounter in our daily life, which affects our perception and understanding of sound. Whether you’re listening to music, watching a movie, or making a call, sound plays an important role. However, sometimes we may hear some abnormal sounds, which is the embodiment of sound distortion.

Sound distortion refers to an undesirable change in the transmission or amplification process of the sound signal, causing the original clear and real sound to become distorted, distorted or noisy. This can affect the pitch, quality and overall perception of the sound, reducing our accurate understanding and enjoyment of the sound’s message.

Speaker distortion is a common form of sound distortion. Speakers are devices that convert electrical signals into sound, and they play an important role in playing sound. However, due to the physical characteristics and working principle of the speaker itself, as well as the problem of signal transmission, the speaker will also experience distortion during operation.

here are several main types of speaker distortion:

Harmonic Distortion: This is one of the most common forms of speaker distortion. When the speaker is amplifying the sound signal, it may generate additional harmonic components, making the original sound richer, but it may also cause sound distortion and make people feel that it is not clear enough.

Crossover Distortion: Speakers usually use multiple drive units to play sounds of different frequencies. Crossover distortion can occur when these units are switched, resulting in interrupted and choppy sound.

Phase Distortion (Phase Distortion): There may be phase differences between different parts of the speaker, resulting in phase distortion of the sound, making the positioning and layering of the sound blurred.

Compression Distortion: When a speaker processes a high-intensity sound signal, compression distortion may occur, that is, the high-intensity part of the sound is compressed, resulting in a smaller volume difference and affecting the dynamic range of the sound.

Distortion rate (Total Harmonic Distortion, THD): The distortion rate is an index to measure the degree of speaker distortion, which indicates the proportion of harmonic components in the speaker output. The lower the distortion rate, the less distortion the speaker will have.

To reduce speaker distortion, manufacturers usually take a series of technical measures, such as using high-quality materials to manufacture speakers, optimizing the design and layout of speakers, applying digital signal processing technology to correct distortion, and so on.

All in all, sound distortion is a problem we often encounter when using speakers, which affects our perception and experience of sound. Understanding the causes and types of sound distortion can help us better select and use speakers and improve our appreciation and enjoyment of sound.
