Ultrasonic Tank Wall Linings (20 kHz to 10 MHz)
Acoustic output measurements or ultrasonic testing in general can be strongly affected by reflections or echoes from test tank walls. This is particularly true for long toneburst or continuous-wave ultrasonic applications. To overcome this, test tanks should be coated with linings which must be of low ultrasonic reflection yet highly absorbent to ultrasound. The current range of materials have been designed specifically to meet these requirements spanning a frequency range of 20 kHz to 10 MHz. Research continues towards expanding the operating frequency range.
