Living in a Box
RMS levels of broadband noise with decreasing sound volume in ten steps of 6 dB (blue bars) in reference to the noise floor (green boxes) for all recording setups. The lower and dark green part of the boxes represents the masking threshold. Noises with intensities (blue bars) above the green masking floor are audible without masking. In cases with higher flow rates, a high proportion of the stimuli are masked.
incubator only a few noise steps are audible.
