Sound at The Ritz-Carlton Residences, South Beach: the slab between neighbours, the walls, and the rules for hard floors

In a concrete tower the neighbour you hear is usually the one above, walking. At The Ritz-Carlton Residences, South Beach, here is how the building is meant to keep that sound where it starts.

This page is a framework. Whether the building suits you is a separate conversation. Contact the desk at Miami Dossier for the current position on any building we cover.

Two Kinds Of Noise

Through the air and through the slab.

Voices and music travel through the air; walls and floors are rated for them by STC, the sound transmission class. Footsteps, dropped objects and chairs travel through the structure; floor and ceiling assemblies are rated for them by IIC, the impact insulation class. The Florida Building Code sets a minimum for each between residences, and some luxury towers state higher targets. Ask which figures The Ritz-Carlton Residences, South Beach commits to, and whether they are tested on site or only calculated.

The Ritz-Carlton Residences, South Beach: Private elevator with direct entry in most residences; wrap around terraces with glass railings; ten foot ceilings; floor to ceiling windows with Miami-Dade NOA rated systems; Gaggenau appliances; Bianco Rhino marble kitchens; Covelano Silver Gold marble primary baths.

Hard Floors And Underlayment

Stone looks quiet. It is not.

Stone, tile and wood carry impact sound into the slab. Declarations usually require an approved acoustic underlayment beneath any hard floor, and a few require a test once it is laid. Ask what the rule at The Ritz-Carlton Residences, South Beach says, whether the developer’s own finished floors meet it, and whether an owner who renovates must submit the product and its rating to the association before work starts.

The Ritz-Carlton Residences, South Beach: 30 residences over 15 storeys, one to five bedrooms, including two duplex penthouses with private rooftop terraces, pools and kitchens; sales launched February 2025; delivery planned 2027.

The Building’s Own Sounds

Shafts, chutes and machines.

Some noise comes from the building itself: an elevator shaft beside a bedroom, a trash chute behind a wall, pumps, generators and cooling towers on the roof or the amenity deck. Read the floor plans at The Ritz-Carlton Residences, South Beach for what sits on the far side of each bedroom wall, and ask where the mechanical rooms sit in relation to the lines under consideration.

The Ritz-Carlton Residences, South Beach: More than 50,000 square feet: a private double height lobby, 24 hour doorman, concierge and valet, a Level 7 amenity floor with a private lap pool and four semi private cabanas, a Technogym fitness centre, a residents’ beach club with cabana service; restaurant and beach club programming by Jose Andres; à la carte in residence dining, personal chef, trainer, spa, childcare and pet care.

Outside Noise And The Record

Glass, traffic, a written standard.

Laminated impact glass usually cuts traffic and boat noise better than ordinary glazing, and a window’s OITC rating measures that outdoor sound. Ask whether the acoustic targets for The Ritz-Carlton Residences, South Beach appear in the construction drawings or only in the brochure, and whether an acoustic consultant reported on them. The desk asks the developer of The Ritz-Carlton Residences, South Beach for the acoustic specification in writing.

Quiet is a number on a drawing. Ask to see the number.
