Abstract
We have searched for narrow-band-noise (NBN) modulations of the infrared transmission in blue bronze, using tunable diode lasers. No modulations were observed, giving an upper limits for NBN changes in the absorption coefficient of $\Delta \alpha_{NBN} < 0.3 $ / cm ( $\approx \alpha/2000$). The implication of these results on proposed CDW properties and NBN mechanisms are discussed.
