  Motivated by events in which black holes can lose their environment due to
tidal interactions in a binary system, we develop a waveform model in which the
tidal deformability interpolates between a finite value (dressed black hole) at
relatively low frequency and a zero value (naked black hole) at high frequency.
We then apply this model to the example case of a black hole dressed with an
ultralight scalar field and investigate the detectability of the tidal Love
number with the Einstein Telescope. We show that the parameters of the tidal
deformability model could be measured with high accuracy, providing a useful
tool to understand dynamical environmental effects taking place during the
inspiral of a binary system.
