How do I launch and configure the Nightingale?

Use the Nightingale Sound mobile app to configure and register your units, using an active email account. Please make sure to configure your Nightingales and confirm the email on the same mobile device. Once they are configured and connected to Wi-Fi, you can control them through the Nightingale Sound mobile app or through any supported browser at:, logging in with the same user and password to register.

How big a room does a pair of Nightingales cover?

The two units can cover a typical bedroom size of 300 square feet (e.g., 15ft x 20ft). If your room is larger, you can add more units.

Where should I place the Nightingale units?

Plug the units into different outlets in the room. For better acoustic coverage, choose outlets on opposite walls. (Please do not plug units into each other.)

Can I split up a Nightingale pair and use one in another room?

Yes you can split a Nightingale pair and use one in another room as long as each room is 150 square feet or smaller. Each Nightingale unit effectively masks noises in rooms up to 150 square feet. If you have a bedroom more than 150 square feet, we recommend keeping two units in the room for effective sound blanket coverage.

What if I only have one outlet available?

If you only have one power outlet, you can plug an extension cord into the first Nightingale unit, and attach a second Nightingale to the extension cord. When plugging an extension cord into a Nightingale, use the lower plug. If your bedroom is 150 square feet or less, we recommend using the Nightingale Standard.

Can I secure Nightingale to the wall, so it can’t be removed?

Yes, you can secure it to the wall with an optional locking plate. This accessory may be especially useful to people who have Nightingale in rental rooms/properties.

What type of outlet can Nightingale fit in?

Nightingale is certified for use in the typical single gang 110 Volt outlets that are standard in the United States.

What if I’m trying to keep my outlets free for other devices?

Nightingale is a single gang 2-socket outlet pass-through outlet, allowing a Nightingale to be used as a typical wall outlet. Note, you cannot use a GFCI outlet due to the spacing of the prongs. However, you can use an extension cord that has 3 prongs.

What appliances can I plug in through the Nightingale pass-through plugs?

The pass through plug supports up to 15 amps of power.


What if I have Wi-Fi connection issues?

  • If a Wi-Fi connection is not made on the first attempt, please try connecting again.
  • Ensure you Nightingale units are plugged into the wall.
  • Nightingale works on Wi-Fi with a frequency of 2.4 GHz. If you do not have a router that supports this frequency, we recommend getting a one that does.
  • Ensure your Wi-Fi password was entered correctly. Passwords are case sensitive. If your password was entered incorrectly, you will receive an error message.
  • Try restarting your Nightingale units. Unplug the units from the wall outlet, wait 15 seconds. Plug them back into the wall outlets, while holding the reset button on the side of the unit. Release the reset button after 9 seconds. The lights will flash green and a welcome voice will play to confirm the unit has been reset.
  • Try turning your smartphone off, and back on again. Re-launch the Nightingale app.
  • Check Wi-Fi signal strength as shown on the app. Restart your router by unplugging it, and plugging it back in after 30 seconds.
  • Try moving the units closer to your Wi-Fi router. If they connect when moved closer to the router then you may need a ‘range extender’ or ‘repeater’ in your home so the Wi-Fi can reach the room containing Nightingale.
  • Eliminate potential interference. Here is a list of devices that may be causing interference: microwave ovens, baby monitors, wireless security cameras, cordless phones.
  • Reduce the number of devices using your Wi-Fi network at home. Some internet service providers (ISPs) will limit the number of devices (computers/phones...) connected to the network. This may be what’s keeping Nightingale from connecting. If you disconnect other devices from the Wi-Fi and Nightingale can connect, you need to contact your ISP and ask for additional connections.
  • Make sure your router is running the latest firmware. You may need to contact your ISP or router manufacturer to see if there is an update to your router especially if it is more than 6 to 8 years old.

Nightingale works by adding subtle background sounds, optimized to mask common noises, into the bedroom environment. We call these sounds “sound blankets.” Sound blankets help you sleep better by masking outside noises that would normally disrupt your sleep.

My bedroom is quiet, but I still have trouble sleeping, can Nightingale help?

Many people have a hard time falling asleep when it’s too quiet. Nightingale raises the ambient noise level of your room, helping you sleep when it’s too quiet.

How do I reset my units?

Caution: re-setting your units will set them back to the factory defaults and you will lose all settings. You will have to set up the application again before you can use them.

To reset your device, unplug it from the wall, and wait ten seconds. Then, holding the button (look for a square button on the right side of the unit, as you look at it from the front), plug the unit in, holding the button 9 seconds, then let go of the button. If the unit received the reset it will flash the light, and a few seconds later it will play the welcome message asking you to download the Nightingale Sound app. If the reset didn’t work, please try again.

Why did I lose power to my Nightingale?

If you have a dual plug wall outlet where the bottom outlet power is controlled by a wall switch, then your Nightingale will shut off when you turn of the corresponding power switch (e.g., turning off the lights at night). This is because the Nightingale receives its power from the bottom outlet. (Most outlets with a wall switch connection have that connection only on the top outlet, which is not a problem, but sometimes an electrician may wire the power switch to the bottom outlet.) Additionally, if the outlet is physically mounted upside-down, so that the ground pins are above the blades, this may prevent power from reaching the Nightingale. In short, find an outlet that has power coming from the bottom even when you turn the power switch off.



Where can Nightingale be useful?

You can use Nightingale anywhere that background noise is a problem. Common locations include bedrooms, infant/toddler rooms, hospital rooms, and hotel rooms.

How does Nightingale work?

Nightingale works by increasing the background noise in a listener’s environment, thus reducing his sensitivity to bothersome noises.

What is included with Nightingale?

Nightingale includes two units and a Quick Start Guide.

Why does Nightingale have two units?

There are two units so that the Nightingale sounds can more effectively immerse the listener within the room environment. Other sleep devices are comprised of a single unit, often placed right next to the user on a nightstand. This single-unit setup results in a localizable sound, where a user can pinpoint the device generating the sound. With two units, Nightingale can act like a pair of stereo speakers, to fill the room more uniformly.


Can you use Nightingale in Canada or elsewhere outside the US?

Nightingale is currently only certified for use in the United States and Canada. We do have plans to extend Nightingale’s coverage to other countries.

Can I play my music through it?

Nightingale was designed to improve sleep, it was not designed for music playback. As such, it acts as a speaker only for the sound blankets and soothing nature sounds that come with it.

How is Nightingale different from other sleep devices like white-noise machines?

Nightingale represents a new category of personal sound-masking solutions for the residential market.

It delivers professional-level acoustic room treatments to ensure better health through better sleep.

It is controlled from a mobile app and integrates with popular smart-home appliances and IoT platforms, unlocking endless personalization and control capabilities.

With two units per room, Nightingale’s sound masking completely fills the room. In contrast, conventional sound machines produce noise from a single unit, so that a user is easily able to localize on the sound. Nightingale’s sound masking is thus more pleasing and more effective at blocking disturbing noises.
