I just use REW for easier accessibility. Here is the exact same data, slightly different analysis parameter for higher resolution. Two data correspond quite well with one another.
BTW this is what happens when you over-pressurize a transducer driven with constant-pressure. Most of the time, BA types with same SPL have far less decay.
Very interesting! Do you have other decay measurements for comparison? ER-4 and maybe another dynamic or BA type IEM.
