Fig 1.
Speech test setups for (a) speech or music testing in quiet (S0 or M0), (b) speech in noise S0N0, (c) speech in noise S0N0T0, (d) speech in noise S0N±45N±135, and (e) speech in noise S0N±45N±135T135 (note: transient noise presented ipsilaterally to ear with the CI). Orange speaker icons indicate target signal (speech or music), black speaker icons indicate stationary noise, and the blue speaker icons indicate transient noise.

Speech intelligibility in quiet with each configuration.
Boxplots show median values as well as first and third quartiles. Whisker bars show minimum and maximum values within 1.5 interquartile ranges below and above the first and third quartile. Diamonds show outliers.

Speech understanding scores (in mean, standard deviation, and range) in quiet and speech reception threshold (SRT80) for each device and setup.
Fig 3.
SRT80 observed in the OLSA S0N0 for each configuration.
A cross marks a significant difference compared to S2.Sonnet. A star marks a significant difference compared to the SONNET. Boxplots show median values as well as first and third quartiles. Whisker bars show minimum and maximum values within 1.5 interquartile ranges below and above the first and third quartile. Diamonds show outliers.
Fig 4.
SRT80 observed in the OLSA S0N0T0 for each test configuration.
Boxplots show median values as well as first and third quartiles. Whisker bars show minimum and maximum values within 1.5 interquartile ranges below and above the first and third quartile. Diamonds show outliers.
Fig 5.
SRT80 observed in the OLSA S0N±45N±135 for each configuration.
A cross marks a significant difference compared to S2.Sonnet. A star marks a significant difference compared to the SONNET. Boxplots show median values as well as first and third quartiles. Whisker bars show minimum and maximum values within 1.5 interquartile ranges below and above the first and third quartile. Diamonds show outliers.
Fig 6.
ACALES results (SNR difference, see text) for a) S2.Mild vs SONNET in S0N0, b) S2.Strong vs SONNET in S0N0, c) S2.Strong vs. S2. Mild in S0N0, d) S2.Mild vs SONNET in S0N±45N±135, e) S2.Strong vs. SONNET in S0N±45N±135, f) S2.Strong vs. S2. Mild in S0N±45N±135.
Positive scores indicate a higher tolerated noise level (i.e., better performance). Boxplots show median values as well as first and third quartiles. Whisker bars show minimum and maximum values within 1.5 interquartile ranges below and above the first and third quartile. Diamonds show outliers.

Product-specific questionnaire results.
Figures are the S2.Sonnet vs. 7a) S2.Mild, 7b) S2.Strong, 7c) S2.AImild, 7d) S2.AIstrong. A point indicates that this percentage of users preferred either the SONNET 2 configuration given on the abscissa, had no preference (None), found the question not applicable (NA), or did not rate (Missing) for the specific listening environment. Higher scores indicate greater preference. Diamonds indicate outliers.
