Regarding the sound absorption coefficients.

[tbelesis]

Greetings! I am trying to simulate an underwater environment with pyroomacoustics. The sound absorption coefficients of media are usually given in either dB/km or dB/100m. What are the units of the air absorption coefficients that exist on the table in the pyroomacoustics documentation? What would be the way to convert coefficients given in dB/km so that they will be suitable for use with pyroomacoustics? Thanks in advance!
