Hearing-Aid Related Variables.

Acronym	Description (units)
REIG50dB	Real-ear insertion gain at 50 dB SPL (dB). Hearing-aid amplification for an international speech test signal (ISTS, Holube et al., 2010) at 50 dB SPL, as measured with the hearing aid placed in the user’s ear.
REIG65dB	Real-ear insertion gain at 65 dB SPL (dB). Hearing-aid amplification for an ISTS at 65 dB SPL, as measured with the hearing aid placed in the user’s ear.
REIG80dB	Real-ear insertion gain at 80 dB SPL (dB). Hearing-aid amplification for an ISTS at 80 dB SPL, as measured with the hearing aid placed in the user’s ear.
RECELO	Real-ear compression exponent at low intensities (dB/dB). It was calculated as follows: 1−(REIG50dB − REIG65dB)/15. Larger values indicate less compression.
RECEHI	Real-ear compression exponent at high intensities (dB/dB). It was calculated as follows: 1−(REIG65dB − REIG80dB)/15. Larger values indicate less compression.
