We examined the interactions between acoustically driven mood modulation and dyspnoea. Following familiarisation, 18 healthy participants attended three experimental sessions on separate days performing two 5 min treadmill tests with a 30 min interval per session while listening to either a positive, negative or neutral set of standardised International Affective Digitised Sounds (IADS). Participants rated intensity and affective domains of dyspnoea during the first exercise test and mood during the second. Mood valence was significantly higher when listening to positive (mean (95% CI): 6.5 (5.9–7.2)) compared with negative ...

Participants rated intensity and affective domains of dyspnoea during the first exercise test and mood during the second. Mood valence was significantly higher when listening to positive (mean (95% CI): 6.5 (5.9–7.2)) compared with negative sounds (3.6 (2.9–4.4); p<0.001). Dyspnoea intensity and affect were statistically significantly lower when listening to positive (2.4 (1.8–2.9) and 1.3 (0.7–1.9)) compared with negative IADS (3.2 (2.3–3.7), p=0.013 and 2.3 (1.3–3.3), p=0.009). These findings indicate that acoustically induced mood changes influence exertional dyspnoea.
