Sound-transmitting waterproof film and method for producing same |
| abstract |
Provided is a sound-transmitting waterproof film having waterproof performance and stable sound-transmitting performance in a wide tonal range. The sound-transmitting waterproof film includes a porous film of a synthetic resin, and has a water pressure resistance of 10 to 400 kPa in accordance with a JIS L 1092 method B (a high water pressure method) and has an acoustic loss of less than 10 dB at a frequency of 1 kHz, an acoustic loss of less than 5 dB at a frequency of 2 kHz, and an acoustic loss of less than 5 dB at a frequency of 5 kHz in sound-transmitting performance tests. |
