It depends on the species very much and of course on how comfortable they are in their nest or in other words wether they think they are safe in their nest or not.
For example my Messor capitatus panic when I lift their box with their testing tube since they normally live in ground only. For contrast my Pseudomyrmex pallidus, who live in trees, don´t seem to notice when I lift their box or when they stand next to my boxes while Messor capitatus sometimes panic when someone in the house uses a drill.
Cataglyphis spp. will panic, too, since they mostly live in deserts and other habitats where there aren´t many vibrations or the ants are very sensitive for vibrations so that they can even feel them in desert sand.
This sensitivity to vibration could partly be caused by the stridulation most (or was it all of them?) ants use. It is a way of communicating without touching or using pheromones. Mostly human ear can´t hear it but in some cases you can. For example Acromyrmex do it so loud that you can hear them without any mechanical help. But once when I moved a Myrmica rubra colony I noticed that you can hear their stridulation, too, when you let severyl workers run over a pice of aluminium foil.
However the vibrations of music and so on will probably affect this way of comunication and cause the ants to panic.
