In order to produce quality audio recordings for a video or movie, it’s important to understand the basic foundations of acoustics. There is a significant difference between room acoustics and building acoustics. Acoustics is defined as, “The properties or qualities of a room or building that determine how sound is transmitted in it.” In other words, acoustics involves how sound bounces from one point to the next and is received by an individual or a recording microphone. Why is it Important to Understand Acoustics in Audio Recording? It is important to understand the basics of acoustics in recording because when you do, you’ll know where the most ideal setup is for microphone and how to capture the sound in the most effective and efficient manner. If you are recording in a close quarter room for example, most ASIC microphones will do a decent job of capturing the sound that you are intending to capture. However, if you are in a small room that is tightly enclosed with no sound absorption, the sound from the characters or the object you are recording will bounce off the walls at different rates, creating an echo. When you step into the video editing stage of production, the echo that is created in the room will become amplified, especially when you attempt to add effects to the audio tracks. When this amplification of echo occurs, it will become a distraction to the audience and will deter from the video that they are watching. As a result, it will also detract from the story line that you’re trying to tell. How sound travels and how fast it travels are important factors to consider when recording. As in the example above, if you are in a small room, such as a 5 x 10 room, you will want to strategically place sound absorption materials along the walls that will capture the sound waves before they can bounce and create the echo you will eventually hear when you begin video editing. There are a number of strategies that you can use to deaden sound and control acoustics. You could use furniture, drapery, or if a section of the room will not be in your shot, you can use foam soundproof material to help deaden the sound. The more that you understand the acoustics involved in audio recording, the better your audio recording quality will become. When you have exceptional audio recording, it should be unnoticed by your audience. When the sound is not noticed by an audience, that means the story takes precedent and your audience members will be drawn in more effectively.
