Result of the general linear mixed models for signal-to-noise ratio (SNR), excess attenuation (EA), tail to signal ration (TSR) of propagated songs of the Yellow-breasted Boubou (Laniarius atroflavus).

Main and two-factor interaction effects are presented for the following source of variation: sex (male, female), location (transmissions STREAM FROM and STREAM TO). Both transects were done on a distance of 25 m only, close to the stream noise and with opposite location of loudspeaker and microphone in each transmission.
