1. A sound wave is a pressure wave; regions of high (compressions) and low pressure (rarefactions) are established as the result of the vibrations of the sound source. These compressions and rarefactions result because sound. a. is more dense than air and thus has more inertia, causing the bunching up of sound.
Software & Apps. Streaming Music, or more accurately streaming audio, is a way of delivering sound without the need to download files of different audio formats. Music services like Spotify, Google Music, and Apple Music use this method to provide songs that can be enjoyed on all types of different devices.
