In this phase, the sound identity is adjusted to the various relevant points of overlap. A further step is to create a sound manual comparable to the prevalent brand manuals, which have been a staple component of all corporate identities for decades.

The advantage of a brand manual lies in the fact that it clearly defines why, how, what, where and when the sound elements are to be used thereby allowing the acoustic presence to be implemented everywhere and at any time through the following elements:

• consistency of implementation
• clarity for those responsible for it
• guarantee of a consistent quality of reproduction
• production of further sound elements in concord with the sound identity
• definition of the points of overlapping and use

The appraisal of success is done by sound monitoring, where it is checked whether the guidelines of the sound manual are being followed. Furthermore, feedback is collected from the listeners. The analysis of the available data allows for readjustment and shows possible further paths of development through measurable results.
