Of course. Two people sitting in your run-of-the-mill supersonic airplane such as the Concorde can easily carry out conversations, without much trouble.

The Concorde's sound at cruising altitude was about 105 decibels, but Buonanno said that based on tests, the X-plane would generate 70 to 80 decibels of noise. Quick and quiet are the buzz words.
No. The sonic boom is the equivalent of a bow-wave on a boat and is continuous behind the supersonic aircraft. An observer on the ground would hear one “boom” as that wave passes by but every point along the ground under the supersonic aircraft will experience the “boom.”
People inside the plane didn't hear a thing. In fact, the transition to supersonic flight was so unimpressive that they decided to install a “mach meter” inside the passenger cabin so that people would know then they passed the speed of sound.
The Concorde was famously loud: a take-off at Washington airport in 1977 measured 119.4 decibels. By comparison, a clap of thunder hits 120 decibels while the pain threshold for the human ear is around 110.
Why don't we ever hear sonic booms any more? Noise abatement regulations halted supersonic flight (by civil aircraft) over U.S. land. The Concorde could still take off and land here because it broke the sound barrier over the ocean, but it's no longer in service.
Such speed didn't come cheap, though: A transatlantic flight required the high-maintenance aircraft to gulp jet fuel at the rate of one ton per seat, and the average round-trip price was $12,000.
The Concorde's retirement was due to a number of factors. The supersonic aircraft was noisy and extremely expensive to operate, which restricted flight availability. The operating costs required fare pricing that was prohibitively high for many consumers.
Concorde is sadly no longer flying, but it is still possible to visit some of the remaining 18 airframes, there are others not open to the public but you can still see them.
Supercharged: Concorde was the first -- and still only -- passenger aircraft that had turbojet engines with afterburners. Raw fuel was introduced into the exhaust of the plane's four engines, immediately increasing the engines' thrust by almost 20%.
Concorde used the most powerful pure jet engines flying commercially. The Aircraft's four engines took advantage of what is known as 'reheat' technology, adding fuel to the final stage of the engine, which produced the extra power required for take-off and the transition to supersonic flight.
Below Mach 1.3, this would dissipate in the atmosphere, but Concorde could 'supercruise' at Mach 2, twice the speed of sound, causing a noise like a thunderclap to be heard on the ground.
Fifty years ago, the federal government banned all civilian supersonic flights over land. The rule prohibits non-military aircraft from flying faster than sound so their resulting sonic booms won't startle the public below or concern them about potential property damage.
The challenges of manufacturing and certifying new parts, maintaining a licensed flight crew capable of flying it, and ongoing maintenance and preservation mean we are no closer to seeing Concorde flying again since its last flight in 2003.
Boom Supersonic, the US plane manufacturer, plans to have the answer with its new Overture jet, which is set to transport customers at twice the speed of today's fastest commercial aircraft, and is regarded as the new Concorde.
flying on the Concorde was not a comfortable experience. this ultra fast supersonic jet. was once revered as the future of business travel, but its interior felt more like flying in a shoebox.
