The aim of this project is to study and identify several dozens of the most valuable bells in our
churches and monasteries, as well as to develop an audio archive (using advanced technologies) for analysis,
reservation and audio data protection.
To accomplish this we have to:
- Document the main bells' characteristics: design, form, type, geometric size, decorative
and artistic scheme, weight, material, state, characteristics of chime, data about the producer
and owner of the bell, estimation of its historical value.
- Take digital photos and video recordings of the bells while being tolled.
- Analyze and record their frequency spectrum during a stroke.
- Analyze and record the bells' frequency spectrum in main tone.
- Create charts representing the sound fade by time, sound stream,
sound pressure and other acoustic characteristics.
- Examine the bells using the methods of supersound fault detection in case fault localization is necessary.
- Analyze collected data and provide instructions on preventive examinations and repairs if necessary.
- Save and protect data in a special archive using advanced methods and technologies.
