Provided is a sound pickup loudspeaker apparatus that has a mechanism for detecting situations in which sound amplification should not be performed and stopping sound amplification from a speaker. The sound pickup loudspeaker apparatus is installed in a vehicle. At least a sound pickup position and a sound amplification position are assumed to be present in the vehicle. The sound pickup loudspeaker apparatus includes a noise level estimation unit that determines a noise level that is an estimated value of the magnitude of a noise component included in a sound pickup signal obtained from a microphone that collects sound emitted from the sound pickup position, and a control unit that performs control such that (i) when the noise level is not greater than a predetermined threshold value or is less than the threshold value, an acoustic signal based on the sound pickup signal is played back from a speaker at the sound amplification position, and (ii) when the noise level is greater than the threshold value or is at least the threshold value, the acoustic signal is not played back from the speaker.
