ATLAS Resonate App 
and Online Tool
for safe listening

Safe listening times can be surprisingly low for some everyday sounds 


Safe Listen Times

The whole day

Normal talk (~70 dB)

6 hr - 10 min

Headphones, Traffic, Lawn mower, Tractor, Motorcycle,  Movies, Concerts, Sports  (80-110 dB)

2 min

Ambulance, Sirens (110-129 dB)

1-0 min

Fireworks, Jet taking off (130-160 dB)

Thus there are Safe Listen Standards to protect from unsafe noise

ATLAS Resonate App

Provides instant environmental and headphone noise exposures vs. daily and weekly safe listen dose

per the Standards

Online Tool

Provides App onboarding, hearing essentials, self-check and self-care information

Customized to (1) 12-17 years and (2) !8 years and older



Sound exposure, measured as decibels (dB), has a nonlinear relationship with safe exposure duration


While less than 85 dB over 8 hours/day is generally considered as safe, it takes a series of computations to determine the decrease in safe times above the level 

The App computes and reports safe listen times based on dB and exposure duration

Use of the App and the Tools, as part of your healthy lifestyle, helps you make decisions for reducing exposure to potentially harmful noise levels and duration*

*Harmful noise levels and long exposure duration can cause Noise Induced Hearing Loss (NIHL)


Monitor your listening 

Use your phone microphone to measure environmental dB 

Get your headphone dB automatically when you connect your headphones 

The App automatically calculates  safe times at that dB  + your exposure vs standardized safe dose 

Do a spot-check or log your exposure duration

See your daily/weekly history - environmental, headphone and combined


Make safe listening choices


Get color-coded outcomes of your daily and weekly exposures 

Check your personal dashboard on your last logged measurement 


Get tips on safe listening and App use  

Get reminders to check your exposure


Get Online Tools for your listening lifestyle  


Customized for adults and older kids*

Onboarding, Privacy, Cybersecurity information
