Distance is the most important factor in the path calculation when we’re outdoors. The intensity of any type of energy is highest close to the source. The same is true of a light bulb, a mobile phone tower, a Wi-Fi connection, etc. You have no doubt noticed that as you move away from a source of sound, particularly outdoors, it gets quieter.

We are going to look at the source-path-receiver relationship in three parts: outdoor acoustics, or what we call a free field environment, where the only thing that affects the path is distance indoor acoustics, where we’ll put the source and receiver in the same room together and try to understand the effect that the room has on and isolated acoustics where we’ll put the source and receiver in separate rooms and look at how the intervening walls and other construction elements affect how much sound gets into a room or gets out of a room. If we want to change the quality or quantity of sound at the receiver, we have to make a change to one or more of these three elements: the source, path, or the receiver itself. Sound is generated by a source, follows some path from source to receiver, and is experienced by the receiver (usually a human listener). Assessing or manipulating any sound can be simplified into what is often called a source-path-receiver analysis. Practitioners of acoustics, or acousticians, want to understand how sound impacts a listener, we look at the path that the sound has taken on its way to the listener from the source. Our experience of sound is always acoustic, regardless of whether electronics were involved in the path from the source to our ears. However, we are not able to hear audio signals until they have been turned back into acoustic signals. Audio is a convenient way to transmit, manipulate, and store sound. In the recording industry, the term “audio” generally refers to an electrical representation of an acoustic signal. Acoustics is the study of sound in some mechanical form-whether in air or some other medium.

It is important that we draw a distinction between acoustics and audio. What is the difference between acoustics and audio? Musicians are primarily concerned with the range of sound that is audible to humans, and that will be the focus of this article. What is acoustics?Īcoustics is the branch of physics concerned with the study of sound, which is simply anything that humans or other animals can hear. Here are some basic ideas in acoustics to begin your studies, which can be beneficial before diving into the more advanced mathematical concepts. If you’re looking to become a better sound or recording engineer, acoustics is definitely something you want to wrap your head around. The following is excerpted from Berklee Online’s Acoustics course, authored by Eric Reuter.įrom outdoor amphitheaters, to indoor concert halls, to sound-tight recording studios, an understanding of acoustics is required to design these spaces and ensure they sound their best when they are filled with live music.
