Microphones are to be placed along the new high speed railway between Amsterdam and Rotterdam to record noise levels when regular services start in September, transport minister Camiel Eurlings said on Wednesday.

Yesterday it emerged more than 1,600 complaints about the noise had been made since trials began earlier this month.
Eurlings said people may be shocked by the noise after looking at an empty track for so many years. ‘Now it is being used by trains. Are people simply surprised or is the noise really above regulations. I want to know,’ the NRC quoted the minister as saying.
The minister said he did not yet know what would be done with the results of the recordings.
The high speed railway has been completed two years behind schedule.
