This document discusses noise control in buildings. It introduces noise and noise control, then covers topics like sound and noise, room acoustics, floor construction, space planning, and noise control for main building equipment. The goal of noise control is to reduce unwanted sound pollution through strategies like addressing noise at its source, using appropriate floor assemblies, and planning spaces to separate noisy and quiet areas. Proper equipment selection and placement can also help control noise from mechanical systems.Read less
Within work zones, you may have echoing group work and gathering spaces, high-volume machinery, or dining and entertainment spaces where the collective sounds drown out your ability to hear the person next to you.

Sound control in commercial buildings refers to the process of reducing noise levels and improving room acoustics for optimal acoustic comfort. It involves using materials, products, and noise reduction techniques to:
What classifies as good acoustical design? Like any aspect of building construction or modification, acoustic needs and fixes must be carefully planned. From impact noise to background noise, consider the following before making an investment in sound control:
According to the EPA, the sound levels you need to speak with others and perform normal activities without annoyance or interruption are 45 decibels indoors and 55 decibels outdoors.1 Measuring current decibel levels environmentally or within your space can allow you to determine what STC level of performance is needed when choosing materials or acoustic solutions.
If you build a perfectly sound (controlled) wall and then cut holes in it, are your efforts out the window? You might struggle between sound and temperature control on one hand, and beautiful natural lighting on the other, but implementing sound control related to windows may include:
With new construction, one way to control door-related noise is to consider placement. If business allows, integrate primary entrances on building sides that encounter less external noise. Similarly, stagger or plan internal entrances to avoid opening toward higher-noise zones.
To get started, measure current external and internal decibel levels over the course of a week. You can opt for a tool such as a sound level meter, noise dosimeter, or octave band analyzer, but a simple app download may be all you need. The CDC recommends the NIOSH Sound Level Meter App, available for free download on any mobile iOS device.2

Commercial music is defined as any music coming from a commercial establishment like restaurants, hotels, or nightlife establishments. It includes live performances or recorded audio content. This guidance document assists establishments that play music with information on a range of acoustical products, vendors, and professional services available to help control sound and vibration in their establishments and buildings. When applied properly, these acoustical tools may be helpful in reducing sound and vibration, and in achieving compliance with the New York City Noise Code, rules and regulations.
Additionally, if you have a noise complaint related to a hospitality industry establishment or are an establishment that is experiencing consistent complaints from residents, the Mediating Establishment and Neighborhood Disputes (MEND) NYC initiative aims to resolve disputes over noise and other quality of life issues using professional mediation services.

The Office of Environmental Quality (OEQ) and the Alexandria Police Department (APD) are responsible for enforcing Noise Control code in the City of Alexandria. An interim noise enforcement procedure has been effective since May 2021 until a more robust and permanent enforcement procedure and resources are implemented. According to this interim enforcement, OEQ is the primary responder for noise complaints during regular business hours (8 a.m. to 6 p.m.) while the Police Department responds to noise complaints during after-hours and weekends. The Noise Control Code can be found in Section 11-5 in the Alexandria City Code. You may download a PDF copy of the Noise Code, or you may obtain a hard copy of the Noise Code by calling 703-746-4065 or by visiting the Office of Environmental Quality, 2900B Business Center Drive, Alexandria.
Please see Sec. 11-5-12 of the Code for more details on civil penalties. OEQ makes every effort to work with individuals to resolve noise issues before resorting to punitive measures.
The Department of Transportation and Environmental Services, through its Office of Environmental Quality (OEQ) administers and enforces the provisions of the Noise Code. The Police Department, Code Administration, and Construction & Inspection Division are also responsible for enforcing the Noise Code.

Unwanted sound is called noise. Sound is perceived when there is a variation of the static air pressure. Compared to the static air pressure, the variations that can be perceived by the ear are very small. The response of the ear is logarithmical rather than linear to the stimuli and therefore the acoustic parameters are expressed as a logarithmic ratio of the measured value to the reference value. This logarithmic ratio is called decibel (dB).
Airport noise is a growing concern among residents in the areas surrounding Reagan National Airport (DCA). In May 2023, the City of Alexandria, in coordination with Fairfax County and Prince George's County, entered a two-year airport noise study with airport noise consultant, Vianair Consulting. This study is focused on the communities south of DCA. This project includes discussions with the Steering Committee and Design team, community engagement meetings, and outreach.
In 2017, The Washington Reagan National Airport launched an Aircraft Noise Community Working Group to identify and implement noise mitigation solutions for National Airport Airplane Traffic over the surrounding communities.
As part of this effort, the Metropolitan Washington Airports Authority (MWAA) voluntarily launched an interactive Community Complaint Dashboard. To submit a complaint, please visit the DCA Reagan National website.
More information about efforts and progress towards mitigating aircraft noise at DCA, through the MWAA Community Working Group (including Alexandria), is located on the DCA Reagan National Website and in the presentation.
Through its participation in the MWAA National Airport Aircraft Noise Community Working Group, Alexandria successfully achieved support for ensuring aircraft flight over the city is minimized. View updated information on the Federal Aviation Administration's advisory to air traffic controllers regarding the use of early turns from National Airport when air traffic is in south flow. Aircraft may only take early turns over Alexandria, rather than flying the prescribed FAA procedure for aircraft flying south from the airport (south flow), to or beyond the Woodrow Wilson Bridge, before turning inland, are only to be allowed in the case of weather changes, safety or national security. The minimization of early turns results in reduced aircraft noise for Alexandria residents 152ee80cbc
