Soundton is a 2D online tool that reveals the best and worst speaker positions for your own room. It's an essential even for small bluetooth speakers, because speaker placement is just as important as the quality of speakers.
Computational Acoustics PhD Andrea Cicero from University of Salford is the mastermind behind Soundton. You can read more about its working principles over at our documentation page.
When assessing the sound quality performance of any loudspeaker for whatever reason, unlike low frequency response which is always given a lot of attention, high frequency response is almost never given any.
The first reason for this is that low frequencies are generally more challenging for loudspeakers to reproduce accurately than high frequencies. This is because low frequency sound waves have longer wavelengths, which means that the speaker cones or diaphragms need to move a greater distance to reproduce them. As a result, it is more difficult to design a speaker that can accurately reproduce low frequencies, and the quality of the speaker's low frequency response is often a good indicator of its overall performance.
Second, low frequencies are more important for the overall sound of music and other audio content. Low frequencies provide the foundation for the rest of the audio spectrum and contribute to the sense of depth and fullness in a sound. As a result, it is important for speakers to have a good low frequency response in order to accurately reproduce the full range of audio content.
Finally, low frequency response is often more noticeable to listeners than high frequency response. This is because low frequencies are more easily perceived by the human ear and are more difficult to mask or hide behind other sounds. As a result, it is often more important for a speaker to have good low frequency response in order to produce a high-quality sound.
Soundton is no different in this manner and rightfully only takes low frequency responses into account.
However, it unfortunately does not happen often. Because we only accept anechoic low frequency response curves in order to achieve the highest accuracy in our simulations, and anechoic chambers aren't common, so it's not easy to get that data.
An anechoic low frequency response curve is a graph that shows how a system or device responds to low frequency sounds in an anechoic chamber. An anechoic chamber is a space that is designed to be completely free of echoes, so that any sound produced within it is absorbed by the walls and ceiling, rather than bouncing off of them.
This allows for highly accurate testing of a system or device's response to low frequency sounds, which are typically difficult to measure in a typical room environment due to the way they interact with the surfaces in the room. The low frequency response curve shows the system or device's response to a range of low frequency sounds, typically at different levels of intensity or amplitude.
This can be useful for understanding how a system or device will perform in different environments, and can help engineers design systems that are optimized for specific applications.
Soundton only uses anechoic (or at least quasi-anechoic) low frequency response curves for accuracy reasons.
Absolutely! This is one of the most powerful use cases of this tool.
The colors in the colormap are fixed. This means that you can run two separate simulations and still be able to make back to back analysis by comparing the tones of the colors.
Rotating the speakers don't affect the results because low frequency sound waves tend to be omnidirectional in reality - meaning that they spread out evenly in all directions from their source.
This is because low frequency sound waves have long wavelengths, which allow them to bend around obstacles and spread out in a more uniform manner than high frequency sound waves. However, the omnidirectionality of low frequency sound waves can be affected by the specific properties of the environment in which they are traveling.
For example, if a low frequency sound wave is traveling through a narrow passage, it may be more directional and focused, rather than spreading out evenly. Additionally, the presence of obstacles or reflective surfaces in the environment can also affect the omni-directionality of low frequency sound waves.
For simplification reasons, Soundton assumes all low frequency responses to be omnidirectional.
