Airbnb Noise Monitoring: Minut, NoiseAware, Party Squasher

Noise monitoring sits in the same category as smoke alarms: most stays do not need it, but the one party that lands without a sensor costs more than three years of subscription. The choice between Minut, NoiseAware, and Party Squasher is less about which one wins on paper and more about which one fits the failure mode you actually care about: noise complaints from neighbors, occupancy violations that precede the noise, or audit trail for an HOA or city ordinance that already requires a monitor.

TL;DR: Minut is the broadest sensor at the lowest public entry price and the deepest PMS integration shelf, which makes it the default pick for 5-20 doors already running Hostaway, Hospitable, or any of its 30+ integrated PMS. NoiseAware is the brand named in many HOA bylaws and municipal ordinances, which matters when the audit trail goes to a regulator rather than a guest, but its pricing is not publicly listed. Party Squasher counts mobile phones rather than measures sound, which is the right answer when the failure mode is twelve people arriving at a four-guest booking before the music starts.

The three platforms at a glance

	What it measures	Public pricing visible	OTA / PMS integration breadth	Best fit
Minut	Noise, smoking, motion, occupancy (via nearby iOS signals), temperature, humidity, security alarm	Yes: $5 / $10 / $15 per home per month, billed annually, plus $10/mo Call Assist add-on (as of June 2026, verify with vendor)	Airbnb official, 30+ PMS including Hostaway, Hospitable, Guesty, Smoobu, Lodgify, OwnerRez	5-20 doors running a mainstream PMS, broad coverage at a known price
NoiseAware	Decibel-based noise (indoor and outdoor units), reportedly smoking and humidity on newer units	Not publicly listed at the time of this analysis (pricing gated to sales contact)	Hostaway marketplace lists NoiseAware as a noise-monitoring partner	Operators whose HOA or city ordinance names NoiseAware specifically, or who want the longest-standing US brand
Party Squasher	Device count: number of mobile phones detected via the router, with a user-set occupancy threshold	Not publicly listed on the homepage (pricing page gated, plans referenced as Standard up to 6 properties and Pro up to 1,000)	App can connect to listing calendars for guest contact info; no PMS marketplace presence comparable to the other two	Detached single-family homes where occupancy violations are the leading party indicator and where neighbor noise complaints are the secondary risk

Pricing and feature availability verified from each vendor’s public pages as of June 2026. NoiseAware’s pricing page returned an access block to direct fetching at the time of this analysis, so all NoiseAware claims here are limited to publicly indexed product positioning, not specific price points.

What Minut actually detects

Minut sells a single multi-sensor device (the M3) that does more than noise. Per Minut’s product positioning as of June 2026, the sensor detects sound pressure, smoking risk (cigarette and marijuana smoke patterns), occupancy via nearby iOS signals (not microphones, not cameras), temperature, humidity, mold risk, tamper, and home alarm status. The sensor does not record audio; the public product page describes the noise feature as real-time insight into sound levels rather than recording or transcription.

For a 5-20 door operator, the practical consequence is that Minut covers four failure modes with one device: parties (noise plus occupancy), guests smoking indoors (a recurring source of damage claims and review penalties), HVAC and humidity issues that turn into mold cases over multi-week vacancies, and unauthorized entry while the property is vacant. None of those four is the same insurance claim, but they share the same hardware and the same dashboard.

The pricing structure published on Minut’s pricing page as of June 2026 is unusually transparent for this category: Starter at $5/month per home (billed annually at $60/year, single property), Standard at $10/month per home (with OTA integrations including Airbnb, 30-day data retention, multi-property, team access), and Pro at $15/month per home (PMS integrations with 30+ platforms, unlimited data retention, advanced reporting). Verify pricing with the vendor before purchase. A Call Assist add-on at $10/month per rental unit covers 24/7 guest calling in English and French, which is the difference between an alert that lands in your phone at 2am and an alert that someone else handles.

The 30-plus PMS integration list on Minut’s integrations page as of June 2026 covers most of the systems a 5-20 door operator would actually be running: Hostaway, Hospitable, Guesty For Pros, Smoobu, Lodgify, OwnerRez, Hostfully, Cloudbeds, Mews, and Uplisting among them. The integration breadth matters because it removes the question “does this sensor talk to my stack” from the buying decision.

Where NoiseAware fits

NoiseAware is the brand most often referenced when an HOA, city ordinance, or property owner contract names a specific noise-monitoring product. The brand recognition value is real, and operators in markets with prescriptive STR ordinances (parts of California, Texas, and Arizona historically) sometimes find that NoiseAware is the path of least friction when a permit application requires evidence of a noise-monitoring installation. The Hostaway marketplace listing for NoiseAware as of June 2026 describes the product as “a privacy-safe noise monitoring solution that alerts property managers when volumes in their rentals exceed reasonable levels, ” which is the standard category positioning.

What this analysis cannot do, in honesty, is give you a public NoiseAware price point. Attempts to fetch the NoiseAware pricing page returned an HTTP 403 to direct access at the time of writing (June 2026), which means the pricing details visible to a logged-in or sales-qualified visitor are not visible publicly. Operators evaluating NoiseAware should expect to enter a sales conversation rather than self-serve onboard. If your HOA or city ordinance specifically names NoiseAware, that conversation is worth having. If not, the inability to compare prices in advance is a real friction relative to Minut’s published tiers.

The product line is positioned around indoor and outdoor decibel sensors rather than the multi-sensor approach Minut takes. The single-purpose design has historically been the brand’s selling point: do one thing (noise) well, with a focused dashboard and a focused alerting workflow.

What Party Squasher does differently

Party Squasher does not measure sound. It counts phones. Per Party Squasher’s homepage as of June 2026, the device is a small sensor (described as a 2-by-2-by-1-inch unit) that connects to the local router and detects nearby mobile devices, calibrated to distinguish on-property phones from neighbors based on signal size. The mobile app and the alerting layer fire when the count exceeds a host-set threshold for the booking.

The operational consequence is meaningful: a four-guest booking with twelve phones present is almost always a party invitation that has not yet escalated to noise. By the time decibels rise above the alert threshold on a Minut or NoiseAware sensor, the party is established and intervention takes longer. Party Squasher’s branch of the failure tree targets the earlier signal, when the host or co-host can still pre-empt the event by contacting the guest, citing the booking party size, or in some cases triggering a same-day cancellation through the platform’s anti-party tools.

The plan structure visible on the homepage references a Standard tier (up to 6 properties via mobile app) and a Pro tier (APIs and web dashboard, up to 1,000 properties), but no public prices appear on the homepage. Pricing requires a follow-up on the pricing page itself. The product is explicitly not suitable for shared-wall buildings (apartments, condos, attached townhouses) because the sensor cannot reliably separate phones on the property from phones in neighboring units. For detached single-family homes (the typical US STR profile in suburban and rural markets), the constraint is not a problem.

The PMS integration story is the weakest of the three: the app can connect to listing calendars to pull guest contact details, but Party Squasher does not appear in the Hostaway marketplace noise-monitoring category alongside Minut and NoiseAware, which suggests that PMS-native integration is not the buying path. For operators who already standardize on a PMS-driven access stack (as covered in our smart locks for STR operators guide), Party Squasher is an additive sensor, not a replacement for the broader monitoring layer.

False positives and what they actually cost

The marketing for every noise monitoring vendor emphasizes accuracy. The published data from each vendor on false positives is essentially zero: none of the three vendors publishes a measurable false-positive rate on their public pages as of June 2026. Operator-side experience reported in STR forums (Reddit, Hospitable community threads, and similar) clusters around three failure modes that any sensor in this category eventually produces.

Threshold-related false positives. A daytime vacuum cleaner, an evening dinner party for four guests in a four-guest booking, or a TV at normal volume can trip a sensor configured too tightly. Each false alert is a non-zero operational cost: time to investigate, time to message the guest, and the small but real reputational risk if the guest realizes a sensor is logging their activity. The fix is conservative threshold setting (typically the vendor’s default is reasonable for the first month, then tuned upward if needed) and the use of multi-minute averaging rather than single-spike triggers.

Occupancy-related false positives. Party Squasher’s device-count model registers the cleaner’s phone, the maintenance contractor’s phone, the delivery driver’s phone, and the neighbor whose phone the sensor calibration did not exclude. The vendor’s signal-size calibration handles most of the neighbor problem, but a sensor configured aggressively will flag a routine service visit. The fix is calibration of the property baseline (most vendors do this during onboarding) and tolerance ranges that account for known service traffic.

OTA-policy false positives. The most consequential false signal is one that drives an over-eager operator to message a guest accusingly about noise that the sensor recorded but the neighbor did not. The cost is a one-star review, an OTA penalty, or both. The mitigating practice for 5-20 door operators is a two-signal rule: do not contact a guest about noise unless either (a) the sensor data shows sustained breach (more than 15 minutes above threshold, not a brief spike), or (b) a neighbor complaint corroborates the signal. The operational template for managing reviews after an incident is covered in our Airbnb review management playbook for 5-20 doors.

The Airbnb disclosure rule and the HOA leverage

Per Airbnb’s safety devices policy effective April 30, 2024, hosts are permitted to install noise decibel monitors in the home’s interior, with two restrictions: the monitors cannot be in bedrooms, bathrooms, or other sleeping areas, and their presence must be disclosed in the listing’s safety devices section. Unlike exterior cameras, the disclosure does not have to specify the exact monitor location. The policy applies to decibel-only sensors that do not record audio, which covers all three platforms in this analysis.

The practical disclosure path is two lines in the safety devices section of every Airbnb listing where a sensor is installed, written plainly: “noise decibel monitor in main living area, does not record audio.” Skip the disclosure, and a guest who discovers the sensor (a battery change, a service alert visible in the room, a visible device LED) has both an Airbnb policy complaint and a contemporaneous reason to leave a one-star review.

The HOA and city ordinance leverage runs in the opposite direction. In markets where short-term rental permits or HOA bylaws require evidence of a noise monitoring installation (parts of California, Arizona, Texas, and Florida have included such requirements in various municipal codes over the past five years), the sensor is not a host preference, it is a condition of operation. The audit trail is the value. NoiseAware’s brand recognition with regulators has historically been a tailwind for permit applications in markets that name a specific product, though confirmation always belongs to the local permit office, not to vendor marketing. The Paris licensing comparison covers a parallel example of how a regulator’s choice of specific compliance mechanism changes the cost of operating.

Verdict by segment

Solo and small operator, 1-5 properties, detached homes. Minut Standard at $10/month per home (billed annually, verified June 2026) covers the four most common failure modes (noise, occupancy, smoking, climate) with one device and a clear price. The Pro tier is overkill at this scale unless the PMS integration is specifically required. Skip Party Squasher unless the property has a documented party-risk history, in which case stack it alongside Minut on the highest-risk doors.

Growing operator, 5-20 doors. This is the segment where the buying decision actually matters. The default pick is Minut Pro at $15/month per home (verified June 2026) for the PMS integration shelf, which removes operational friction when the sensor talks to Hostaway, Hospitable, or whichever PMS the portfolio runs. Add Party Squasher on detached doors with party risk above the portfolio average. Use NoiseAware only when an HOA bylaw or city permit explicitly names it, because the inability to compare prices publicly and the narrower detection model do not pay back at this scale absent that constraint.

Pro and portfolio, 20-50 doors. The sensor cost stops being the variable. The dashboard, the response workflow, and the audit trail become the cost centers. Minut’s PMS-integrated alert routing wins on operational scale, especially when paired with a Call Assist tier or a dedicated co-host on the response side. For portfolios with regulatory complexity across multiple jurisdictions, NoiseAware’s regulator brand recognition can still be the path of least friction in the markets where it is named. Party Squasher remains additive: on the doors where party risk is the dominant failure mode, run both.

Mixed-portfolio operator with shared-wall units. Party Squasher is structurally not the right answer for apartments or attached condos (the vendor’s own product description excludes them). Minut and NoiseAware both work, with Minut winning on integration breadth and published pricing, NoiseAware winning when the local regulator specifies it.

The damage-protection layer that catches what monitoring does not is covered in our STR damage protection guide. The lock and access management layer that fires before the noise sensor ever does is in the smart locks for STR operators guide. Sensors are one piece of the prevention stack, not the whole answer.
