Introduction:
People with hearing loss complain of listening to music (Caldwell et al., 2015; Hopyan et al., 2016), and it is even more challenging to perceive the emotions of music (Picou et al., 2018). Although a large body of studies are focused on the perception of musical emotions in people with hearing loss, the underlying cortical mechanisms for the perception of musical emotions in people with hearing loss are unclear. In this study, to investigate the effect of audibility, we measured cortical activity response to the emotional perception of music.
Methods:
Normal hearing group (NHO) and simulated high- (NHH), and low- (NHL) frequency hearing loss groups were created by using original stimuli and applying low-, and high-pass filtering (1000 Hz cutoff) to musical stimuli, respectively. A total of 48 healthy participants were randomly assigned to three groups (16 people / group). Fifteen musical stimuli developed in our lab were used for the study. The pre-evaluated stimuli (Lee et al., 2023) were composed of five melodies, and each melody was expressed differently according to emotions including happiness, sadness, and neutrality. During 64-channel EEG recording, participants listened to the randomly presented stimuli binaurally via two speakers followed by ratings of arousal and valence (dimensional model) and selecting emotions (discrete model, thus named discrete). A total of 300 trials were conducted 20 times repeatedly for 15 stimuli.
Results:
The NHL group had lower ratings for arousal than the NHH group and for valence than the NHH and NHO groups. To examine the effect of hearing loss, we performed a time-frequency analysis and dynamic imaging of coherent source (DICS) analysis comparing three groups. We also applied surface Laplacian spatial filtering to reduce volume conductivity before time-frequency analysis. We selected trials according to the rating criteria of arousal and valence (happy>7, sad<4, and 4<=neutral<=6) and the percent corrects of emotions. As a result, the topography of the NHL group showed higher alpha activity in parietal channels than the other two groups in all emotions for arousal, valence, and discrete. Therefore, we chose parietal channels to examine the differences of alpha activity among three groups in time-frequency analysis. There are non-significant differences among the three groups with cluster-based permutation tests nonetheless showing increased alpha activities in the NHL group. However, in the DICS analysis, the alpha activity of the NHL group was significantly higher than the NHH group in the right parietal and temporal areas after 2 seconds of stimulation onset in happy stimuli rating over the criteria of valence conditions.
Conclusions:
The composer of these stimuli expressed sadness with a slow tempo. This might make it easy for all participants to distinguish sad stimuli, which could lead to non-changing alpha activity among groups. However, in the happy stimuli which were differentiated among groups, the results of DICS analysis suggest that high-frequency audibility rather than low-frequency audibility affects alpha activity response to the perceived emotion of music.
