摘要
The present invention relates to a sound absorbing sheet having excellent sound absorbing performance and surface decorative effects. The sound absorbing sheet of the present invention is characterized by comprising a base and having an average sound absorption of 0.4 or higher in a frequency range of 200 to 2000Hz. The permeability and air porosity of a base layer of the sound absorbing sheet of the present invention may be adjusted, thereby achieving significantly superior effects of sound absorbing performance despite the thinness of the sound absorbing sheet.
