The noise floor produced by loudspeaker speakers that cannot be eliminated is often referred to as the "noise floor". This noise floor is related to the working principle of the speaker itself and external environmental factors. Here are some of the possible causes of noise floor and the difference between noise and floor noise:
1.Noise from electronic components: Electronic components inside the horn, such as amplifiers, circuit boards, etc., may produce tiny electronic noise. These noises can be caused by the working process of circuit components, current flow, etc., and are difficult to completely eliminate.
2.Electromagnetic Interference: Horns may be subject to electromagnetic interference from power lines, other electronic devices, wireless communications, etc. These interfering signals may be amplified by the horn and converted into sound, resulting in the creation of a noise floor.
3.Ambient noise: Speakers capture noise in the surrounding environment, such as the hum of electrical equipment, the noise of fans, indoor echoes, etc. Even small ambient noise can become a noise floor when amplified.
4.Speaker sensitivity and design: Some speakers may be more susceptible to external noise due to their design or sensitivity. For example, a high-sensitivity speaker may be more likely to pick up tiny signals, including noise floors.
Difference: Noise: Noise is any unwanted sound, whether from the outside environment or from the device itself. Noise can be continuous, intermittent, high-pitched, or low-frequency. In a speaker speaker, noise can be a sound composed of a variety of factors such as floor noise, electronic noise, and ambient noise.
Noise floor: Noise floor refers to a low level of noise that persists and is difficult to eliminate. In loudspeaker speakers, noise floor usually refers to the low-level noise that is produced when there is no other sound input. The noise floor may be related to factors such as the working principle of the speaker itself, the noise of electronic components, the external environment, etc., which may affect the clarity and accuracy of sound quality.
While noise floor usually can't be completely eliminated, there are ways to mitigate its effects, such as using high-quality audio equipment, isolating speakers and power cords, and adjusting volume levels to minimize noise floor removal.
The more powerful the speaker, the more difficult it is to eliminate the noise floor for several reasons:
1.Influence of Signal-to-Noise Ratio: The signal-to-noise ratio refers to the ratio of an audio signal to background noise. In loudspeakers, at higher power, the amplifier increases the amplitude of the audio signal, while also increasing the potential noise floor. If the noise floor is relatively low, the signal-to-noise ratio may remain acceptable. However, if the noise floor level is high, as the volume increases, the proportion of the noise floor relative to the audio signal also increases, making the signal-to-noise ratio decrease.
2.Increased noise from electronic components: Amplifiers and other electronic components produce a certain amount of electronic noise when they are operating. When the power is high, this electronic noise also increases accordingly. This may include thermal noise, current noise, etc. of the amplifier. These noises are amplified and become a noise floor, especially at higher volume levels.
3.Increase in electromagnetic interference: High-power loudspeakers may be more susceptible to electromagnetic interference, interfering signals from power lines, other electronic devices, or wireless communications. These interfering signals are introduced into the loudspeaker system and may be amplified and appear as a noise floor.
4.Self-noise of horns: Some horns may produce their own noise when operating at high power, such as mechanical noise caused by the movement of the diaphragm. These noises can be more pronounced at higher powers.
So, overall, high-powered speakers may increase the ** and intensity of the noise floor, making it more difficult to eliminate. To reduce the noise floor, consider using high-quality speakers and amplifiers, improving the signal-to-noise ratio, avoiding electromagnetic interference, and setting up audio equipment correctly.
