Tone Activations for Hotel and Resort Guest Experiences

A hotel or resort is full of moments where a guest needs one small piece of information: where the pool towels are, when the restaurant opens, what is on at the spa today, which ballroom the keynote moved to. Signs and front-desk staff cover a lot of it, but not everything. Inaudible tones give a property another way to help. A speaker in a lobby, outlet, or event room plays a tone tied to that space, and the property's own app, for guests who opted in, shows the information that fits where they are. Here is how it works across a property, and what to plan before a pilot.

Where tones fit on a property

A tone works best where guests already gather and already have a question. Common starting points include:

• Lobby and arrival. A welcome message, mobile check-in reminders, or a property map in the guest's app.
• Restaurants and bars. Today's menu, hours, or a reservation link, shown when a guest walks into the outlet.
• Pool and cabana areas. Towel and cabana info, food and drink menus, or the day's schedule.
• Spa and fitness. Class times, treatment menus, and booking links.
• Meeting and event spaces. Session agendas, room changes, and sponsor content for group business. Our post on inaudible tones for conferences and trade show booths covers event planning in more depth.

Each space can have its own tone, so the app can show content that matches the area rather than one generic screen.

Start with the guest, not the technology

A property tone program succeeds when it saves guests a step. Before choosing locations, map the guest journey from arrival to checkout and list the questions guests ask most at the front desk, the concierge, and the outlets. The best tone moments answer those questions in the place guests ask them. Keep each moment short, useful, and easy to ignore.

Guest privacy and consent

A phone has to listen to recognize a tone, so the app needs microphone permission, and both iOS and Android ask the user before granting it. Tone moments work only inside an app the guest already chose to use, such as the property's app or its loyalty app with tone detection built in.

• Explain the value first, such as faster answers about amenities and dining, before the system permission prompt.
• Keep it optional. The app and the stay should work fully for guests who say no.
• Be clear about what is used. Tell guests in plain language what the app does when it detects a tone, and follow the property's privacy policy and legal review.
• Keep guest rooms private. Focus tones on public areas such as lobbies, outlets, and event spaces.

Our consent and permission UX checklist for tone apps walks through the permission flow step by step.

Guest safety comes first

Phones should never pull attention away from where guests are walking or driving. Plan tone moments with that in mind:

• No prompts at the driveway, valet, or parking garage where guests may be driving. Save arrival content for the lobby.
• Avoid pool edges, stairs, and busy walkways. Place tone moments where guests are already seated or standing still.
• Keep content glanceable. A guest should be able to read it and put the phone away.
• Never replace safety information. Emergency instructions, signage, and staff announcements stay exactly as they are.

Plan the audio for each space

Hotel spaces sound very different from one another. A quiet spa, a lively pool deck, and a ballroom during a general session all need their own test. Plan for:

• Existing speakers. Confirm the speakers in each area can play the tone cleanly before adding hardware.
• Background noise. Music, fountains, crowds, and HVAC can affect detection. Test at busy times, not just when spaces are empty.
• Outdoor areas. Pools and patios lose sound to open air, so placement matters even more.
• Overlapping zones. Where two spaces meet, test the area between them so the app shows the right content.
• Device range. Test on a mix of guest phones, not just one model.

Results depend on the space and the equipment, so every property pilot starts with an on-site test.

Keep content current

Hotel information changes daily: outlet hours, pool schedules, event room assignments. Assign an owner for each space's content, connect updates to the systems teams already use, and check the content after every change. A tone that points to yesterday's schedule hurts the guest experience more than having no tone at all.

Measure what guests actually use

Because each space has its own tone, results can be broken down by area and by time of day. Track how many opted-in app users were detected in each space, how many opened the content, and what they did next, such as booking a spa treatment or viewing a menu. Compare against the same period before the pilot. Our guide to measuring opt-in rates for tone-triggered campaigns lays out the full funnel.

Frequently asked questions

Will guests hear the tone?

GhostTones tones are designed to be inaudible to most people, so they can play in a lobby or outlet without changing what guests hear.

Do guests need to download an app?

Yes. Tone moments work only in an app the guest chose to use and gave microphone permission to, such as the property's own app.

Can tones work at a pool or other outdoor areas?

Outdoor spaces can work, but open air and background noise affect detection, so they need an on-site test with the actual speakers first.

Can GhostTones help plan a property pilot?

Yes. GhostTones works with hotels, resorts, and their agency partners to plan tones, speaker tests, the consent flow, and reporting.
