Talker echoes are one of the influencing factors which need to be addressed during migration of telecommunication towards wideband transmission. A recently carried out talking and listening test (TALT) focusing on wideband echo disturbances is introduced and the results are summarized. The E-Model, a planning tool for telecommunication networks, considers the degradation of the speech quality c...

[1] We use narrowband images of Titan obtained in November 1999 to explore the haze vertical structure in Titan’s lower atmosphere. The images were taken with the MountWilson 2.54m telescope using the NASA/GSFC-built Acousto-Optic Imaging Spectrometer. These images were recorded at five wavelengths surrounding the 0.94 mm methane window and are sensitive to a range of altitudes in Titan’s lower...
