Response in the ultrasonic range (170 kHz - 2.8 MHz) of venting materials for MEMs air-coupled acoustic/ultrasonic transducers: Sabeu TRAKECTH PET VENTS

Ultrasonic transmission coeffcient (magnitude), in dB, (measured in air at normal incidence) versus frequency of SABEU membranes used for acoustic venting applications. These data permit to determine the response of these vents in the frequency range 180 kHz - 2.8 MHz. Data for three types of membranes are collected: 040-290; 040-300; 040-470 Data of interest for the packaging of MEMs air-coupled ultrasonic transducers. In particular for the venting protection. Data obtained within the Listen2Future project. Project Listen2Future funding is acknowledged. Under grant 101096884, Listen2Future is co-funded by the EU and by the Project Ref. PCI2022-135060-2 funded by CIN/AEI/10.13039/501100011033 and by EU “Next Generation EU”/PRTR.
