1.1 Please describe your problem, which you want to solve with acoustic sensors, shortly.

1.2 Please describe the process shortly (e.g. conveyance on a belt and subsequent falling into a box).

1.3 What should be distinguished?

2.1 How is the sound to be evaluated produced?

2.2 Please describe as precisely as possible the point of sound production (mechanical process of sound production, materials, geometries, temporal course).

2.3 Do you have any sketches, drawings, pictures, videos, animations? (if so, which ones?)

3.1 Try to describe the sound verbally (relative pitch and volume, comparison with generally known sounds, perceived sound form (ringing, scratching, scraping, grinding, hissing, whistling, clicking, knocking, cracking, ...).

3.2 Is the sound continuous or limited in time? If limited, does the duartion vary and what is the repition rate?

3.3 Is there one or more sounds that should be detected?

3.4 Is it possible to clearly distinguish the different sounds (or the good/bad sound) with the ear? Try to describe the difference verbally.

3.5 Can a qualitative statement be made about the reproducibility of the sound(s)?

3.6 What materials are involved?

4.1 What kind of background/extraneous noise occurs in addition to the known sound? What is the perceived volume ratio at the proposed sensor location?

4.2 Are there critical operating conditions (working temperature range, maximum humidity, splash water, dusts, aggressive media, mechanical stress ...)?

4.3 Are there any technical standards that must be complied with?

4.4 For sound detection, a redesign of the process is necessary (seperation of parts, shielding against interfering noise).

4.5 Is seperation possible? (Usually also necessary, e.g. for sorting and for clear sound recognition)

5.1 Characteristics of the power supply

5.2 How/with what should the further processing of the sensor signal take place?

Possibly other further processing:

5.3 Dynamic parameterisation of the sensor during operation is required:

5.4 A connection to a bus system is desirable/required:

5.5 Process signals that allow a temporal assignment of the sound (that can be generated synchronously to the sound, for example) are available:

6.1 Sound samples can be provided (e.g. as audio files):

Sound sample details:

6.2 The sound can be produced under laboratory conditions:

6.3 On-site measurements are possible:

6.4 In the laboratory or during on-site measurements, good or bad sounds can be generated specifically:

6.5 There are already preliminary studies on the use of acoustic sensor technology:

If so - which:
