Testing methods used for assessment of buildings considered as a cultural heritage are focused mainly on non-destructive testing methods. Old buildings are usually sensitive to destructive in-situ testing, and a variety of non-destructive techniques (NDT) are frequently used [1; 2]. One of the most often used sensors are accelerometers, which can measure vibrations of different part of structures. These can be used in either continuous monitoring or in short-time assessment. ImpactEcho is a well-known method which can locate defects, caverns, or damaged parts not only in industry-level structures, but also in preservation of cultural heritage [3]. This type of measurement requires attaching a sensor to the surface of the observed element. This is in most cases done by adhesives which can damage the more porous structures. In this paper a comparison of two different sensor types in testing of reference concrete elements is presented: contact piezoceramic accelerometer; non-contact MEMS type microphone. Signals recorded by each sensor type are assessed by the statistical method of feature extraction.
