What are the environmental factors that affect speaker playback?

Release time：2023-04-07

Usually when appreciating the sound quality of a set of speakers, the most important thing is the hardware factors such as electronic devices, speakers, and wires. In fact, there are many other factors that are not easy for us to find, such as: speaker sound feedback, external vibration, resonance of the listening environment, and acoustic characteristics of the listening room. Speaker sound response.

When playing speakers, the sound waves emitted by the speakers will vibrate the walls, ceilings and floors, and some will even directly or indirectly impact the speaker components. These vibrations are fed back to the components in different ways; for example, the speaker frame, air, etc., at different speeds and intensities, causing the components to vibrate and produce their own resonance, resulting in subtle changes in the electronic flow of the operating sound system in the electronic circuit, which changes the sound, making the sound slightly fuzzy and causing slight distortion.

Environmental resonance characteristics: Objects have their own inherent resonance frequency depending on their material, shape, and size. When external vibration energy is added to the object, if the frequency is equal to or close to its resonance frequency, the object will synchronously vibrate violently and become resonant. Is there any way to eliminate or reduce the inherent resonance of the listening room so that its frequency response appears flat and the speaker system has excellent sound?

This is a physical property of the object that cannot be eliminated, but can only be weakened. For example, a rectangular room is easier to deal with resonance, while a square room will produce standing waves that are particularly difficult to deal with. External vibration factors: If the listening room is near the roadside, factory, construction site, elevator room, pump room, etc., it is very easy to be disturbed by noise or ultra-low frequency, and the speaker components will be unclear due to the vibration.
