Expert's Reports
	ADA prepares Expert's Reports in cases where planning tasks are only in the preparatory phase or if other offices are entrusted with the planning and ADA provides only special support. Such Expert's Reports correspond in their quality and character mostly to a simplified design planning and can thus be used as a basis for budget assessments. Therefore the reports include all fields covered by ADA Acoustic Design Ahnert: - Sound design by means of computer simulation - Audio / video equipment - Media equipment - Room acoustics by additional use of computer simulation Moreover, Prof. Ahnert is a publicly appointed and certified expert for electroacoustics, particularly for sound-reinforcement, mixing-console, video and alarm systems. By video and alarm systems we understand such installed in cultural buildings and other public facilities. Expert's Reports on antiburglar and other alarm systems are not prepared.
