Sound color (timbre) - what it is and what it depends on?

Basics of acoustics

The attribute that allows distinguishing between sounds of the same pitch and volume but coming from different sound sources. Timbre depends on the sound spectrum, meaning the content of the harmonic frequencies, their quantity and intensity, as well as their synchronicity, the shape of the sound envelope, the shape, and the rise time of the sound.

To better imagine what the color of sound really is, one can invoke its analogy to the color perceived by sight.

To better imagine what the color of sound really is, one can invoke its analogy to the color perceived by sight. Just as vision perceives colors based on the spectral composition of light, the color of sound also depends on the proportions of individual frequencies in the spectrum of the acoustic signal. The color of sound largely determines the subjective perception of a given sound. The human ear distinguishes the color of sound based on the ratio of the amplitude of the fundamental tone to the harmonic tones. However, there is some difficulty in naming a particular color of sound. Nevertheless, there are a few concepts that serve this purpose. For example, a bright color refers to a sound characterized by a high content of components with high frequencies, while a dark color refers to a sound that has few of the aforementioned components in its spectrum.

Nyquist Team

The Nyquist team is a group of enthusiasts in acoustics, design, and technology who combine engineering knowledge with aesthetic sensitivity every day. We create solutions that improve acoustic comfort and give spaces a unique character. On the blog, we share our experiences, knowledge, and inspirations drawn from our daily work on projects carried out across Poland and abroad. We believe that good acoustics is not just a technique – it’s a way of creating spaces where one simply enjoys being.

The measurement, conducted with a sound intensity probe, collects a considerable amount of raw measurement data, which is practically useless for documentation and further interpretation by humans. Therefore, there is a need for a relatively advanced processing of this data to obtain a clear and unambiguous picture of the acoustic insulation defects of the tested object – walls, doors, windows, or their connections.

What do the measurements with the intensity probe look like?

Intensity measurements using a sound intensity probe are one of the most precise methods for locating sources of sound infiltration currently used in construction and industry. Unlike classical measurements of sound pressure level, the intensity method allows for measuring the actual flow of acoustic energy. It not only determines how loud it is in a given location but, above all, how much acoustic energy is actually passing through the tested partition. The direction of energy flow is what constitutes the key difference.
