Metro Access Gate Beep: How loud?

. ()

The city carrier RET has adjusted the beep-volume of the access gates to the Rotterdam metro again after receiving more and more complaints that the beep, which the gates produce when people walk through, was too loud.

The beep had always sounded ‘normal’, but because the visually impaired complained that they did not know when the gates opened for them to walk through, RET adjusted the volume upwards and made the beep sound a bit longer.

reported that after the adjustment, other people complained that the beep was too loud. The carrier has now slightly changed the volume again.
