Publication Date



Purpose: The purpose of this study was to preliminarily investigate the sentiments associated with consumer opinions of personal sound amplification products (PSAPs). Method: Online reviews of 21 popular PSAPs were collected from the Amazon.com website. The reviews for each product were exported to compile individual product-specific text files. A sentiment mining analysis was completed to aggregate the number of positive and negative comments for each product. In addition, the effect of value for money, available features, perceived benefit, and overall perception of PSAPs was evaluated. A correlational analysis was completed to examine the relationship between different PSAP features and the number of positive and negative comments. Results: Mixed-model analysis of variance showed a significantly higher number of positive comments for high-and mid-cost products in terms of overall perception and perceived benefit compared to low-cost products. For feature attribute, high-cost products had significantly higher positive comments compared to mid-and low-cost products. There was a strong correlation between price and positive comments and a moderate correlation between price and negative comments. Also, there was a significant moderate correlation between presence of compression and feedback suppression PSAP features and positive comments. Conclusions: Positive sentiments expressed toward PSAPs were found to favor high-and mid-level products. However, there was a considerably high number of negative sentiments reported across all the PSAPs investigated. The noticeable thing is that the negative comments do not change significantly across price ranges. However, the positive comments significantly increase with an increase in product price range. This indicates a possible increase in benefit with high-cost products. However, this claim requires further empirical evidence through controlled studies.
