Noise generated from rocket launches varies greatly for different launch systems. For horizontal launch systems that take off under jet power, the initial noise is similar to other aircraft operations. It is unlikely members of surrounding communities would hear rocket noise from horizontal launch operations, as rocket ignition would occur over open water at significant distances from land. While noise from vertical launch operations would be audible, it would be temporary, infrequent and only loud enough to result in minor impacts like disruption of conversations.
