Disclosed are a sound absorbing sheet having a micro resonant structure and capable of improving sound absorption performance up to the low frequency band by means of the micro resonance principle, a method for manufacturing same, and a sound absorption type soundproof panel using same. The sound absorbing sheet according to the present invention has multiple uneven patterns configured to have convex parts and concave parts on one surface of a porous base material, and the area ratio of the concave part determined by the following formula 1 is 40 to 99%. The area corresponding to the concave part has a lower air permeability than the area corresponding to the convex part.Area ratio of concave portion=[area portion of concave portion]/[area portion of porous base material].&#x2003;&#x2003;[Formula 1]

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 2000 Hz. 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.

A ceramic filter and method for preparing the same. The method for preparing the ceramic filter according to the present invention is characterized in comprising the steps of: (a) coating firstly a ceramic green paper prepared by using a slurry solution comprising ceramic fiber of 0.1-10 mm length, with an aluminum silicate solution and drying the firstly coated paper; (b) coating secondly the dried ceramic green paper with an aluminum phosphate solution and drying the secondly coated paper; and (c) calcining the dried ceramic green paper obtained from the step (b). The ceramic filter according to the present invention has excellent mechanical strength since the bonding strength between ceramic fibers is very high, and shows good porosity, gas permeability, and efficiency for capturing microparticles since the pores between the ceramic fibers are less blocked, and thus can be very usefully applied to gas exhaustion system for automobile.
