AtlasIED Atmosphere pacifies neighbours of Swedish ice rink

Atmosphere platform dampened noise from ice skaters on the Zinkensdamms IP's winter ice rink, in Stockholm, Sweden, after neighbours complained

AtlasIED’s Atmosphere platform was used to prevent the loud noise from the Zinkensdamms IP, a multi-purpose outdoor sports venue, in Stockholm, Sweden, from disturbing neighbours, following a series of complaints. The main problems with noise were during the winter months when Zinkensdamms IP was turned into an ice skating rink by covering it in an inflatable “bubble”, or dome ,to protect the ice skaters and rink surface from inclement weather. Unfortunately, the bubble is not soundproof.

To reduce the audio to a reasonable level, the ice rink proprietors turned to Robert Nilsson, the owner of local AV integrator Dat AB, to recommend and install a solution. He immediately considered AtlasIED’s Atmosphere platform to correct the venue’s issues. “The primary concern was limiting the volume to avoid disturbing the neighbours,” said Nilsson. “However, there really needed to be two zones set up — one for the ice rink itself, which needed to be louder because of the ambient noise, and a second, quieter zone for the spectator areas.”

The Atmosphere AZM4, a four-zone digital signal processor, controls the audio distribution. Using the AZM4, Nilsson can create up to four zones across the ice arena, including the rink and spectator areas. Using Atmosphere, he could limit the maximum volume level for each zone, capping each at 87dB instead of the previous system’s 105dB, which was much too loud, given the proximity of the audience and surrounding neighbourhood.

Nilsson installed an Atmosphere C-V volume controller rinkside to provide local volume control. He also installed an Atmosphere A-BT Bluetooth wall audio input that allows personnel with access to the system to connect their phone via the A-BT to stream music.

The ability to remotely manage the system was another benefit for Nilsson when choosing Atmosphere for the Zinkensdamms IP project. “It is very easy for me to access the system from my office in Säter, which is about a three-hour (200 km) drive to Stockholm,” said Nilsson. “The ability to access the system, troubleshoot, and hopefully solve the issue remotely saves time and money on service costs. It’s a major benefit for everyone.”

A second AZM4 is installed in the operations room, connected through AtlasIED1544AIO-D Dante converters that interface with the fire alarm system. If an alarm is triggered, the AZM4 mutes all zones so everyone in the ice arena can hear the alarms. There are future plans to play a pre-recorded message if the fire alarm is activated.

“The ice rink’s been using the Atmosphere system for over six months, and I haven’t received a single trouble call,” said Nilsson. “Atmosphere just works.”
