How is the impact of reflective surfaces on sound often expressed?

The impact of reflective surfaces on sound is often expressed in decibels. When discussing sound, decibels (dB) serve as a logarithmic unit measuring sound intensity and pressure levels. Reflective surfaces alter how sound waves behave in a given environment, thus affecting the perceived loudness and clarity of sound.

For instance, sound reflections can enhance certain frequencies, leading to increased decibel levels at specific points in a space, such as in a concert hall or recording studio. Understanding this impact is crucial for industrial hygienists assessing workplace environments, as excessive sound levels can lead to noise-related health issues.

While Hertz pertains to the frequency of sound waves and is relevant to understanding sound characteristics, it does not directly express the impact of reflections in terms of intensity or loudness. Physical distance pertains to the spatial relationship between sound sources and receivers but does not quantify the reflective properties of surfaces. Frequency ranges describe the spectrum of sound without addressing how those sounds interact with the environment, which is better captured through measurements of decibels.
