History leaves a lot of evidence. We can look at the ruins of defeated civilizations, think about the bones of the dead, and read about all the cool parts that were glossed over in elementary school. One thing we can't do so much is hearing the sounds of the distant past, but that hasn't stopped people from filling in the gaps. Through scans, anatomical examinations and, in many cases, through the wonders of 3D printing, scientists and sound engineers have brought dead, animals and instruments to life so that they can hear the modern world.

8 A bunch of extinct birds
The New Zealand National Museum Te Papa opened the Te Taiao exhibition Birds in May 201
Above can be seen how the call of a Haast eagle may have sounded, as reproduced by sound engineer Piers Gilbertson. Gilbertson began to utter a golden eagle and changed its pitch. Unfortunately, according to Gilbertson, the end result sounded like "a big, angry chicken". Then he turned to the Wahlberg eagle and, in collaboration with his sound designer Chris Ward, slowed the duration of the Wahlberg call while maintaining his frequency range.
As already mentioned, the eagle call of the Haast can be heard above. Click the link in brackets at the end of this sentence to hear replicas of the Moa, Finsch duck, New Zealand goose and Huia. 
7 Panpipes from Roman Egypt
Listen to it here
In March 2018, University of Kent researchers successfully printed a working replica of a number of panpipes from Roman Egypt in 3D , The original (and extremely fragile) pipe was scanned in collaboration with several institutions along with a number of other ancient instruments. The ultimate goal was to exhibit the sounds of the replica instruments at the Petrie Museum of Egyptian at University College London Archeology.
It was not possible to simply build a new line of pipe pipes for the project. Finding reeds in the desired size would have been almost impossible. Other materials were needed. A bamboo replica was made, but the winning material was a biodegradable thermoplastic. When the 3D printed replica was tested, it was found to be playing a musical scale known to exist in Roman Egypt, according to ancient writings.
Dr. Ellen Swift, a member of the project team, described the finding as a "real moment", although the researchers were surprised at how high the panpipes sounded. 
6 Ancient Greek music
In ancient Greece you didn't have to look far to find music. There is still a lot of documentation. Despite a wealth of information on instruments, notes, scales, etc., it was more difficult to determine the actual sound of ancient Greek music. The original sources describe the music in completely different terms than a modern musician would be used to. In the past, what could be reliably interpreted and re-created sounded strange to say the least.
Dr. Armand D’Angour from Oxford University tried to clear up the confusion. He analyzed a papyrus that was found in 1892 and contains part of a choir from the piece Orestes which dates from 408 BC. BC was written by Euripides. The score on the papyrus was bizarre by western standards, using quarter-tone intervals. According to the professor's analysis, these quarter-tone intervals were considered "passing notes", and the choir itself was actually tonal. He also showed that the music was "word painting", for example a falling cadence paired with the word "complaint".
After three years of effort, Dr. D & # 39; Angour 2016 reconstructed the music on the papyrus. Another help for his work was the replication and playing of some well-preserved copies of the Aulos a wind instrument that was rather ubiquitous at that time. This has given much insight into the pitch of ancient Greek music. In 2017 the play Orestes was performed by a auditorium accompanied by a choir. 
The dead spoke in 2020. In less dramatic (but realistic) terms, scientists managed to recreate the voice of a 3000-year-old Egyptian priest named Nesyamun in January. The vocal tract of the mummy in question was well preserved and suited a man whose coffin read: "Nesyamun, true to the voice". The mummy's neck was CT scanned and a replica of the vocal apparatus was 3D printed. This replica was connected to a loudspeaker connected to a computer, which produced the sound to be passed through.
The end result was an "eeeeehhh" tone, although according to Dr. David Howard, a University of London, a very realistic linguist. It would be more difficult to repeat the sound of Nesyamun's words. For one thing, the mummy's tongue didn't hold nearly as well as its neck. Knowing more about Nesyamun's voice articulations would also help, not to mention more insight into the timing and spoken language of his language. Dr. Howard believes, however, that in the future it may be possible to generate whole words in the voice of the mummified priest. 
4 The Acoustics Of Stonehenge
Listen to this here
What Happened Stonehenge Sounds Like Over 4,000 Years Ago? Of course not like today. Stones fell over or were taken away, which changed the acoustics. In 2019, Dr. Trevor Cox of the University of Salford, a man with an interest in acoustic archeology, such as sound in 2200 BC. Chr echoed through Stonehenge, with all of its original stones present. This was accomplished using detailed Stonehenge laser scans to 3D print a 1:12 copy of the ancient site. The Mini-Stonehenge was placed in an acoustic research chamber and exposed to sounds that were played at 12 times its normal frequency.
Dr. Cox found that, although the monument as a whole was open-air, it sounded like an enclosed space. The sound would have repeatedly bounced off the stones and the voices inside would have sounded stronger. The effect would probably have seemed quite impressive to the people back then. The next step for the team of Dr. Cox will be testing the acoustics of Stonehenge elsewhere as it exists. 
3 The Iceman
Nesyamun is not the only mummy whose voice has been recreated. The same thing happened in 2016 with Ötzi, the famous "Iceman", who was found in the mountains of South Tyrol in 1991. In this case, Rolando Füstös from Bolanzo General Hospital CT scanned the neck of the Iceman. An MRI would have been preferable, but it would have required moving the fragile mummy. Instead, software was used to move the body virtually. This software was also helpful in reconstructing Ötzi's hyoid bone and alleviating the fact that one of his arms was over his neck.
As with Nesyamun, there were restrictions: not all of the soft tissue in the Neolithic mummy's vocal tract was preserved, and the tension in his vocal cords was unknown. The language of Iceman is also unknown. Nevertheless, the researchers used software and mathematical models to simulate how Ötzi's voice might have sounded. The vowels produced were between 100 and 150 Hertz, which was not unusual for a human man, although they were surprisingly pebbly. 
2 Woolly Mammoth Vocalization
Listen here (three minutes in the clip on the linked page)
In 2010 Marguerite Humeau found out about a complicated robot mouth designed by a researcher named Hideyuki Sawada would have. The device had movable lips, a flexible windpipe and “lungs” in the form of an air tank. A video in which the mouth sang a lullaby made its rounds on the Internet. Humeau had the idea of doing something similar with extinct animals.
Her first effort was to reconstruct Lucy's voice box, the famous Australopithecus afarensis. She didn't have much to do since Lucy was only part of her skeleton. With the help of paleontologists, an ear, nose and throat doctor, and a doctor who had performed a larynx transplant, Humeau still built the best Lucy voice box that she could make from resin, rubber, and silicone.
While working on Lucy Humeau had another idea: to replicate a woolly mammoth's vocal tract. Marguerite consulted again with experts, including elephant vocalization specialists and Bernard Buigues, who worked with mammoth preserves, and built an impressive 6m device to mimic the vocalization of the extinct mammal. Both the Lucy and Mammut voice boxes were exhibited at the Royal College of Art in London in 2011. Apparently the mammoth's low rumble has startled a number of children.
1 The T-Rex & # 39; s Rumble
It is believed that Tyrannosaurus Rex may not have roared in movies like Jurassic Park so how could it have sounded like? Chris Packham was looking for an answer in 2017 as part of a documentary to be broadcast on the BBC. For this purpose he turned to Dr. Julia Clarke, Professor of Vertebrate Paleontology at the University of Texas.
Dr. Clarke used Chinese crocodiles and the Eurasian Bittern's reputation, which was enlarged to a T-Rex size animal, to assess how the dinosaur might have sounded. Scans of a fossil tyrannosaur brain shell were also taken into account, which provided insight into the animal's hearing. It appears that the T-rex could hear very low frequencies, possibly even below the human hearing range. According to Packham, the carnosaur's utterances were "so quiet that you would not only have heard it, but would also have felt it."
of the above video. It's a very deep rumble that the T-Rex probably didn't even have to open its mouth to. It is very different from the roar of Jurassic Park but it still manages to get annoying. This is for Dr. Clarke makes perfect sense: “I have the feeling that this sound only triggers fear. People think you need a roar to be really scary, but that's the most scary sound you've ever heard. I don't know if we have a deep-seated adaptive response to low-frequency noise, but I wouldn't be surprised. "
