At a Glance

The City of Longmont recognizes music festivals to be an important contribution to city vibrancy and viability, but cause noise pollution for nearby neighborhoods. Working with new sound monitors, the city intends to be able to see real time sound data and begin developing new smarter sound based civic services.

Problem Addressed

The nightlife economy makes an important contribution to city vibrancy and viability. From entertainment districts to hospitals, “life at night” is part of how we live, work, and play in urban places. Nightlife contributes to culture and economic development, though also presents challenges for public safety, transportation, and quality of life.

Valuing the night economy while navigating its downsides raises a number of questions for cities.

As entertainment venues and music festivals become more prominent in close proximity to community residential areas, friction around sound levels arise. It has become extremely common everywhere to see conflict occur around venues and festival between residents, event producers, enforcement officials and sound engineers over sound levels.

Attaining a near or real time understanding of urban sounds is an increasing challenge faced by communities around the world. Whether for the purposes of nightlife economy, quality of life, or public safety sound has not been a tool available to many cities until now.

City of Longmont used/is using a smart sound level monitoring solution called SmartVenue™ to address this/these challenge(s).

Solution(s) Used

In an effort to understand how sound from live music venues or events, such as the Lefthand Brewing Foundation High Five events which occur throughout the summer concert season, propagate through and beyond the venue into neighboring communities, the City of Longmont is partnering with Archethought to use SmartVenue™ around public spaces.

The city intends to deploy SmartVenue™ sound level monitors at multiple areas around town, and public parks where festivals are held, to capture sound pressure level data, relay and store that data in the cloud giving near real time sound level data access to sound engineers, event producers, code enforcement officials, and community members.

As part of incremental project work the City of Longmont also wishes to explore the advanced capabilities of SmartVenue™ pertaining to sound recognition. Sound recognition may be used to enhance public safety applications, augment venue permitting and ordinance applications, or provide real time insight to traffic safety applications.

Initially the partnership will be to help the City of Longmont get greater insight into sound level data around venues and festivals, but as a result of prior collaborations Archethought and the City of Longmont are now collaborating on the development of new intelligence applications. These efforts will help the City of Longmont work to fix the noise conflict dynamic, and help communities gain a new level of intelligence and understanding into how sounds will impact their daily lives.


  1. Increased Responsive and Engaged Communities - sound monitoring helps communities engage residents in beneficial conversation that disrupts noise conflict dynamics reducing noise complaints.
  2. Increases Nightlife Economy Vitality - accessible and transparent sound monitoring helps nightlife venues harmonize with local neighborhoods and improve reputation within the community.
  3. Urban Intelligence from Sound - 24/7 sound monitor deployments, and intelligence applications introduce new ways to understand how daily life sounds impact our health and safety.
  4. Improved Quality of Life - urban sound monitoring helps combat noise pollution fostering quieter communities reducing rest period interruptions.

Something Unique

The City of Longmont is fortunate to be a leader in smart city infrastructure in the US, and is looking to this infrastructure and new innovations to enhance public safety and service.

Who Should Consider?

Any city that has outdoor venues, hosts music festivals, and are looking for smarter ways to help residential and entertainment communities co-exist, also those communities looking to understand urban sounds.
