Risonanze

Posted on July 30, 2020 at 4:05 AM

Secondo lo studio condotto nel 1976 dall’aviazione militare americana Mechanical Resonant Frequency of the Human Eye ‘In Vivo’ (che ovviamente non aveva intenti di ricerca pacifici) in presenza di una frequenza di circa 18 Hz, il globo oculare umano entrerebbe in risonanza.

Il fenomeno è stato brillantemente studiato da Vic Tandy nel suo articolo The Ghost in the Machine del 1998. In questo studio si giunge alla conclusione che stati di ansia e apparizioni di fantasmi possano essere generati dalle basse frequenze emesse da motori meccanici.

Normalmente gli esseri umani sono incapaci di percepire suoni al di sotto dei 20 Hz quindi questi suoni sono giustamente percepiti dal nostro corpo (non dall’orecchio) come non-umani. 18 Hz corrisponde circa ad un re un po’ calante nel nostro temperamento moderno, due ottave sotto il re grave cantato da una voce di basso. Sarà interessante notare che il ruggito della tigre si aggira appunto sui 18 Hz (per cui noi udiamo solo gli armonici superiori mentre i nostri occhi risuonano di terrore).

Gli studi su questo tema si sono moltiplicato recentemente sino a creare delle mappe di risonanza del corpo umano: versione moderna dell’uomo vitruviano.

Esiste anche un movimento abbastanza recente che si batte contro l’inquinamento prodotto dagli infrasuoni correlando gli studi sugli effetti delle basse frequenze sul corpo umano con le emissioni sonore delle turbine eoliche.

Si può notare che il petto risuona a frequenze udibili (50-100 Hz) e questo spiega anche il perché certi bassi generati da potenti sub-woofer siano percepiti (con fastidio) come una pressione proprio nella regione del petto.

La domanda interessante è se esistano altre parti del corpo che risuonano a frequenze udibili (20-20K Hz) e nel caso, in che modo i fenomeni acustici abbiano influenzato la parte estetico-culturale della musica.

Needed to post you the little bit of observation so as to thank you very much once again for your unique things you've featured on this website. It was tremendously generous with people like you giving publicly all that a number of us could possibly have sold as an e book to make some dough for their own end, most notably since you might well have done it in case you wanted. The pointers as well served as the good way to know that other individuals have a similar zeal just as my personal own to understand very much more with regard to this problem. I'm sure there are several more pleasurable situations ahead for people who discover your site.

I and also my friends were actually viewing the excellent points from your website and so the sudden I got an awful feeling I had not thanked the web site owner for those strategies. The guys were definitely warmed to study them and now have truly been making the most of these things. Appreciate your truly being indeed kind and also for selecting some very good guides millions of individuals are really desperate to discover. My personal honest apologies for not expressing appreciation to sooner.

I wish to show appreciation to this writer for bailing me out of this issue. Just after surfing around throughout the world-wide-web and getting strategies which are not helpful, I believed my life was over. Living without the solutions to the difficulties you've resolved all through this review is a crucial case, as well as the kind that might have adversely damaged my career if I hadn't encountered your web blog. Your own competence and kindness in dealing with every item was crucial. I don't know what I would have done if I hadn't encountered such a point like this. I can at this time look ahead to my future. Thanks a lot very much for the specialized and result oriented guide. I won't hesitate to refer the sites to anybody who should have direction about this problem.
