## What is Noise Score 2?

From the sound of the wind rustling through the trees to a jackhammer cracking through the pavement, our daily lives are filled with sounds ranging from quiet to loud, which results in an environment that can be either relaxing or stressful. Research has established that the environmental soundscape has a large impact on our stress levels, our sleep, and our cardiovascular and mental health. Unfortunately, the unreasonably high sound levels we encounter daily is often met with nonchalance, while the quiet places we can escape are neither publicized or promoted. It is believed that noise is a sacrifice we make for living in a motorized and industrialized society. Therefore, very little information is available for us understand the spatial, temporal, and visual distribution sound in our communities.

The NoiseScore application was designed to address this lack of information by utilizing smart phone technology to capture both the objective and subjective nature of the sounds you encounter as you go about your daily routine.

With the Noisescore application, you can:
• Objectively describe your daily soundscape by measuring sound levels
• Subjectively describe your daily soundscape by answering a brief survey

This information can be utilized to:

• Understand the spatial and temporal distribution of sound levels and noise perception in your community both overall and by specific sources such as loud parties, road traffic, or aircraft noise.
• Identify both quiet and loud spaces you can escape from or travel to
• Allow for your voice to be HEARD and your issues to be seen.

Some considerations:

1. The NoiseScore sound level meter measures an unweighted sound pressure level—the dB. One of our primary research goals is to study total noise—that is, we want to capture the contribution of low and high frequency sound as well capture both the noise we hear and feel.
2. Our sound level meter is in an experimental phase and is being subjected to continuous review and improvement. We welcome any feedback and appreciate your patience as we test and update.
3. While we have carefully tested this application, you may experience issues. Please keep in mind that this application is a work in progress and your feedback helps us to improve it. If you do experience issues, please reach out to us.

The NoiseScore application is a community research project developed and maintained by Noise and the City, an advocacy group founded by Erica Walker, a postdoctoral researcher at Boston University School of Public Health in the Department of Environmental Health.

### 1/5 — Impossible to sign in

*2025-07-08*

Whoever made this app is not paying attention. Someone else had the same problem a year ago. Honestly people! If your app is getting one star, don’t you wonder why?

### 5/5 — works great

*2024-01-23*

cool app for a cool project! simple and easy to use. i’m looking forward to learning about what information is gathered and what can be learned from the work being done (and hopefully action that can be taken). thanks for looking out for all the beings, human and otherwise who are sensitive to sound and for people who don’t have much of a choice in how much noise they’re subjected to everyday.

### 1/5 — Cannot sign up after downloading app

## Frequently asked questions about Noise Score 2

### What is Noise Score 2?

Noise Score 2 is a community research project that uses smartphone technology to measure sound levels and collect subjective feedback on noise perception. It helps users understand the soundscape of their community and identify quiet or loud areas.

### How does Noise Score 2 measure sound?

Noise Score 2 measures an unweighted sound pressure level in decibels (dB). The developers are interested in capturing the total noise, including low and high frequencies, and both audible and felt sound.

### Is Noise Score 2 accurate?

The sound level meter in Noise Score 2 is in an experimental phase and is continuously reviewed and improved. While tested, users may experience issues, and feedback is welcomed to help with updates.

### What is the purpose of the surveys in Noise Score 2?

The surveys allow users to subjectively describe their daily soundscape. This information, combined with objective measurements, helps in understanding noise perception and its distribution within a community.

### Can I use Noise Score 2 to report specific noise issues?

Yes, the data collected can be utilized to understand noise perception by specific sources like loud parties, road traffic, or aircraft noise, allowing your voice and issues to be seen.

### Is Noise Score 2 free to use?

Yes, Noise Score 2 is available for free. It does not have in-app purchases or advertisements, making it a completely free tool for users.
