Music at outdoor concerts organised by Swansea University students' union will finish earlier, and won't take place on Sundays, following complaints after last summer's end-of-year bash.
The students' union said it had been working closely with licensing authority Swansea Council on future events at Abbey Meadow, Singleton Campus.
Events with amplified music as the main component will now take place on a Monday to Saturday only. The music will finish at 11pm or before.
A phone number will also be provided for residents most likely to be affected by the music during the duration of future events.
Also a method of dispersing students must be submitted to a safety advisory group where the attendance exceeds 500 students.
A students' union spokeswoman said: "Our future events held at the Abbey Meadow will now take place on a Saturday as opposed to a Sunday.
"Any amplified music at the events will also finish before 11pm to help minimise any noise or impact to our local community and families.
"We hope that these changes make a positive difference and we will continue to listen to our community and work with Swansea Council and the local police on all future events."
Last June's 5,000-capacity summer ball took place on a Sunday at Abbey Meadow and featured live performances including The Feeling and Eva Lazarus.
Some residents living two miles away claimed they weren't able to hear their own televisions.
One person living in Uplands said it was "the loudest event I’ve ever heard" and that the music carried on to midnight.
Another resident, in Pinewood Road, Uplands, said they had to close their bedroom window to get to sleep.
“All I was thinking of was the poorly patients in Singleton Hospital," they said.
Uplands councillor Peter May said he fielded 60 complaints and met council officers the day afterwards.
Licensing officers worked with all responsible authorities to agree the new conditions.
"The officers have worked in partnership with the union to put in a new set of conditions," said Cllr May.
"Hopefully these conditions will provide the safeguards that my constituents are entitled to when such events resume."
