In recent years, while overall sales of CDs and other audio products have declined, sales of vinyl records have risen.One of the reasons for the popularity of vinyl records is the so-called 'vinyl record like' of vinyl records, such as warmth and nostalgia.We want to clarify people's impression of the sound quality of vinyl record.In the evaluation experiments, comparisons were made between vinyl record audio and high-resolution audio, and impression evaluation experiments were carried out using the semantic differential method.As a result of the principal component analysis of the obtained responses, it is confirmed that the first principal component consists of brightness and clarity, and the second principal component consists of beauty and power, with a cumulative contribution rate of 0.79.The results of the multiple regression analysis also show that the degree-of-freedom-adjusted coefficient of determination for "not nostalgic nostalgic" exceeds 0.5, which means that prediction is possible with two principal components, and since the first principal component has a higher value than the second principal component, it is considered that the first principal component is mostly predictive.The diagram of principal component scores shows that the record group tends to have a strong impression of gloom and doom in the first principal component.The two points suggest that vinyl records with gloomy and dazed impressions have a nostalgic sound quality.
