Frequency sweep tests
WebThe LAS test includes two parts. The first part is a frequency sweep test (see Section 7.3.1) for acquiring undamaged rheological characteristics of bitumens immediately after applying a low-frequency load and the second part is determining bitumen’s fatigue characteristics implementing different strain levels during 30 min. WebDec 12, 2024 · Using frequency sweep in the audio frequency range, i.e. 20 Hz to 20 kHz, you can actually test the acoustic characteristics of an object or a room. It can be used to test sound absorption or reflection characteristics, or perhaps to test the measurement quality of a microphone or the acoustic quality of a musical instrument and more.
