Etymotic Research will be manufacturing a limited run of ER10 microphone assemblies with three ports. For those that remember them, these will be the size of the original ER10's (about in diameter) but there will be three ports.. This will permit the delivery of three independent tones through three ER2s (e.g., the two primaries and a suppressor in DPOAE experiments). Alternatively one of the ports can be used for an optical fiber to control the placement of a calibration microphone for high frequency stimuli. They cannot put three ports on the smaller ER10B. If anyone is interested in potentially purchasing one or more of these assemblies please contact Laurel A.
