The dataset contains data for 11 young and 10 older listeners with normal hearing (young and older NH listeners).The Readme file provides a description of the dataset's content, and of the related article.The data collected were:Population data: age, tested ear, and reverse digit span scoreAudiogramsHearing threshold at the test frequencyAmplitude modulation detection thresholds with short stimuli durationAmplitude modulation detection thresholds with extended stimuli durationMasked-threshold patterns (MTP; short stimuli duration)Masked-threshold patterns (MTP; extended stimuli duration)Population DataDataset giving the population information for the 21 participants (tp), split into young NH and older NH (group), tested in the study. The data summarizes the participants' age, and tested ear (ear), as well as their Reverse Digit Span score (rds_score). The age is given in years, and the reverse digit span score is given on a normalized scale from 0 to 1.AudiogramAudiometric thresholds (thresh) were collected for 21 participants (tp), split into young NH and older NH (group), at frequencies (freq) of 0.125, 0.25, 0.5, 1, 2, 3, 4, 6, and 8 kHz. The thresholds are given in dB Hearing Level (HL).Hearing ThresholdHearing thresholds collected at the test frequency (2.8 kHz) for all listeners.21 participants (tp), split into young NH and older NH (group) were tested. The thresholds (thresh) were measured across at least 3 repetitions (repetition) for each listener. If the standard error across repetitions exceeded 2 dB, additional repetitions were added until that limit was met. The thresholds are given in dB Sound Pressure Level (SPL).AM DetectionDataset for the amplitude modulation detection thresholds collected with a short stimulus duration (0.6 s).21 participants (tp), split into young NH and older NH (group), were tested. Detection thresholds (thresh) were collected at four different target modulation frequencies (fmod) of 4, 16, 64, and 128 Hz. At least three repetitions (repetition) were collected for each condition. If the standard error across repetitions exceeded 2 dB, additional repetitions were added until that limit was met. In case a threshold was not obtainable in one of the repetitions, the thresh entry specifies "NaN". The thresholds are given for the target modulation depth on a dB scale: M = 20log10(m), where m is the modulation depth on a linear scale.AM Detection ExtendedDataset for the amplitude modulation detection thresholds collected with an extended stimulus duration (1.1 s).21 participants (tp), split into young NH and older NH (group), were tested. Detection thresholds (thresh) were collected at a target modulation frequency (fmod) of 4 Hz. At least three repetitions (repetition) were collected for each condition. If the standard error across repetitions exceeded 2 dB, additional repetitions were added until that limit was met. In case a threshold was not obtainable in one of the repetitions, the thresh entry specifies "NaN". The thresholds are given for the target modulation depth on a dB scale: M = 20log10(m), where m is the modulation depth on a linear scale.Masked-Threshold Patterns (MTPs)Dataset for the masked-threshold patterns (MTPs) collected with a short stimulus duration (0.6 s).21 participants (tp), split into young NH and older NH (group), were tested. Masked thresholds (thresh) were collected at four different target modulation frequencies (fmod) of 4, 16, 64, and 128 Hz, and five to seven different masker-modulation center frequencies (given as octaves relative to the target modulation frequency, mask_oct) at -5, -4, -2, -4/3, -2/3, 0, +2/3, +4/3, and +2 octaves. At least three repetitions (repetition) were collected for each condition. If the standard error across repetitions exceeded 2 dB, additional repetitions were added until that limit was met. In case a threshold was not obtainable in one of the repetitions, the thresh entry specifies "NaN". The thresholds are given for the target modulation depth on a dB scale: M = 20log10(m), where m is the modulation depth on a linear scale.Masked-Threshold Patterns (MTPs) ExtendedDataset for the masked-threshold patterns (MTPs) collected with an extended stimulus duration (1.1 s).21 participants (tp), split into young NH and older NH (group), were tested. Masked thresholds (thresh) were collected at a target modulation frequency (fmod) of 4 Hz, and seven different masker-modulation center frequencies (given as octaves relative to the target modulation frequency, mask_oct) ranging from -2 to +2 octaves, in steps of 2/3. At least three repetitions (repetition) were collected for each condition. If the standard error across repetitions exceeded 2 dB, additional repetitions were added until that limit was met. In case a threshold was not obtainable in one of the repetitions, the thresh entry specifies "NaN". The thresholds are given for the target modulation depth on a dB scale: M = 20log10(m), where m is the modulation depth on a linear scale.Ethical statementAll listeners were financially compensated for their time and gave written informed consent.
