A receiver 18 receives echoes 20 from the item 12. The apparatus 10 measures the frequency spectrum of the echo 20 and makes a comparison with another frequency spectrum to extract information relating to a change in the item 12. For example, the item 12 may wear during use. A comparison of the frequency spectrum, with previous frequency spectra, allows changes of dimension of the item 12 to be identified. Changes in amplitudes of the frequency spectrum allow changes in roughness to be detected."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ultrasonic measurement","description":"Ultrasonic measurement apparatus 10 includes a transmitter 14 to transmit an ultrasonic signal 16 into an item 12.
